Images and halftonesText and typographyVectors and layers
Alter Product's Product Designer: the same cat artwork on a sweatshirt in the 3D view and on its print area in the 2D view.
One design, two views. The composition from the 2D area appears on the 3D product model.

From composition to product

Design in 2D and 3D

Design on a flat 2D area, work directly on the print areas of a 3D model, or use both views side by side. Place and adjust elements while checking their scale and position on the product.

The combined view helps you assess the composition in the context of the product's actual shape. See the same text, image, or motif both as a print design and as part of the finished visualization.

Grid and print preview in 2D

Grid and snapping

Enable the grid and snapping to layers to position elements more precisely.

Preview without the background image

Hide the workspace background image to assess the print itself more closely. Design elements remain visible.

Image above or below the grid

Choose whether the background image appears above or below the grid.

Custom preview background

Replace the image with a white, gray, black, or custom background. Check the edges and transparent areas of your artwork against a contrasting color. The change affects the preview, not the print design.

2D workspace settings in Alter Product: grid, snapping to layers, background image, and preview colors.
The 2D view settings help you assess the print against your chosen background and position elements precisely.

Images, opacity, and composition

A photo, illustration, or logo can be the starting point for your entire design. Adjust its appearance, transparency, and arrangement, then combine it with text and other layers.

Your own artwork

Add JPEG, PNG, and WebP images, as well as SVG files. Replace artwork in your composition to create another design variation.

Opacity from 0 to 100%

Combine motifs, build subtle backgrounds, and control how strongly an image stands out on the product.

Position and transformations

Move, scale, rotate, and flip elements. Adjust their position within the print area in the 2D view or on the 3D model.

Patterns for images, text, and shapes

Patterns from a single motif

Create a repeating pattern from a single element. Use it as a background, decorative motif, or composition within the print area. The repeat tool also works with text and shapes.

Grid

Five repeat layouts with the icons you will find in the app.

Set the number of rows and columns, spacing, and pattern offset. Vary A/B versions with rotation, scaling, or reflection. Alternate elements, rows, or columns, or use a checkerboard arrangement; use a random seed for scatter.

Filters and image adjustments

Match artwork to the character of your collection without leaving the design. The filter panel includes light and color correction, detail processing, halftone, and semitransparency controls.

Image filters and adjustments available in Alter Product
Filter or adjustmentWhat you can do
BrightnessLighten or darken artwork before placing it in the composition.
ContrastIncrease or soften the differences between light and dark areas of an image.
Black and whiteTurn a color image into a monochrome version of your design.
InvertInvert the colors to create a negative effect.
HueShift the color tones to give your artwork a different character.
SaturationControl color intensity - from muted to vivid.
VibranceFine-tune color vibrance as a separate color correction step.
Red gammaAdjust the tonal response of the red channel.
Green gammaAdjust the tonal response of the green channel.
Blue gammaAdjust the tonal response of the blue channel.
SharpenEmphasize edges and fine details in your artwork.
BlurSoften the image for smoother transitions.
HalftoneBuild a halftone effect with dots, crosses, or lines and adjust its structure.
Remove semitransparent backgroundRefine transparency using an alpha threshold and transition softness. This adjustment works on pixel opacity rather than object recognition.

Six halftone styles

Halftone with control over detail

Give your artwork a rhythm of dots, crosses, or lines. Halftone lets you shape the print's structure deliberately, from a fine screen to a bold decorative effect.

Halftone: dots

The same fox artwork with a line halftone rotated by 45 degrees in Alter Product.

Halftone: lines

Fox artwork from the Alter Product library before and after applying the filter. Both examples use spacing 12 px, size 0.9, angle 45°, contrast 1, and softness 0.1 px, with brightness inversion and full opacity enabled. The dark background reveals the transparent gaps in the halftone. Click an image to see the details.

Ellipse

Crosses

Lines

Halftone style diagrams. The effect's appearance in your design depends on the source image and selected settings.

Spacing and size

Set the density of the halftone and the size of its elements.

Angle and contrast

Rotate the grid and adjust how the artwork's brightness affects the halftone.

Edge softness

Choose sharper or softer edges for the elements.

Invert and full opacity

Invert the brightness response and enable elements without semitransparency.

Remove backgrounds and selected colors

Isolate a motif and prepare it to combine with other elements. Start automatically or work manually, and remove a selected color with the eyedropper and tolerance setting.

Automatic background removal

Isolate the main subject of an image to use it in a print without its surrounding background.

Manual mask refinement

Remove and restore areas with a brush. Adjust its size and strength to refine small elements and edges.

Color knockout

Pick a color with the eyedropper in the manual background removal tool. Set the tolerance to remove matching pixels throughout the image, then refine the mask with the brush.

Manual masking step by step

Work on the image mask and control which areas remain visible. Apply the result once the edges and transparency are ready.

Brush and eraser

Hide image areas with the eraser and restore them with the brush. Adjust size and strength, and edge hardness in supported browsers.

Removing a selected color

Pick a color with the eyedropper and adjust the range tolerance. Remove matching areas and refine the details with the brush. In supported browsers, you can also soften the boundary with blur.

Circular mask

Enable a circular mask and change its radius, edge softness, and center position along the X and Y axes.

Review and undo changes

Change the preview background color, zoom in, and pan to assess the edges. Undo and redo operations, or clear the mask to restore the image.

Example use: remove a solid background from a logo, keep just the motif, then place it on a colored product or repeat it as a pattern. Color knockout also affects the selected color inside the artwork, so refining the result with a mask is worthwhile.

From a caption to expressive typography

Text that gives your design character

Create lettering that suits the product, brand, and artwork style. Choose a typeface, reshape the text, and combine a fill with a stroke or shadow.

Over 1800 Google Fonts

Search typefaces by name and filter them by category and supported writing systems. Choose from serif, sans serif, display, handwriting, and monospace fonts.

Typography under control

Adjust size, letter spacing, line spacing, and alignment. Change letter case, apply underline or strikethrough, and use the bold and italic variants available for the typeface.

Fills, strokes, and shadows

Combine solid colors with linear or radial gradients. Add a solid or dashed stroke and a shadow with your own color, offset, and blur.

Four ways to shape text

Standard text

Create simple lettering and multiline compositions with control over alignment and line spacing.

Curved text

Curve the lettering and adjust the arc angle and distance. Build a composition around an emblem or central image.

Bridge text

Change letter height at the edges and in the middle of the text. Control the smoothness of the transition and the vertical position of the center.

Oblique text

Give your lettering direction by adjusting the height at the start and end, as well as the end's vertical position.

Shapes, paths, and vectorization

Combine simple figures into compositions or move on to precise work with points and curves. The path editor refines supported shapes and path layers.

Ready-made shapes

Start with a rectangle, line, ellipse, circle, triangle, hexagon, octagon, or star. Refine the fill, stroke, and shadow; for rectangles, adjust the corner radius too.

Your own outlines

Turn a preset shape into an original emblem, decoration, or outline. Edit points on supported shape and path layers in the 2D view while checking the result on the product.

Point and curve editor: from sketch to precise outline

Select an unlocked shape or path layer and enter vector editing. Work on one layer at a time, drawing new sections or refining the existing geometry.

Pen and path extension

Draw new segments with the pen, join them to existing points, and close outlines. Add new points on a path or remove unnecessary ones to refine the shape.

Point selection and lasso

Choose a single point or select a larger section with a selection box or lasso. Work on the selected part of the outline while keeping other points in place.

Moving along a path

Move points freely or along the existing path. Move selected points together to change an entire section of the composition.

Bézier curves and handles

Shape curves with incoming and outgoing handles. Enable them separately and choose independent handles, handles mirrored by angle, or handles that preserve both angle and length.

Connecting points

Connect selected points with a segment. Extend the path and refine the connections that form your outline.

Cutting paths

Draw a cutting line across a path to split it. Then refine the resulting sections with the point and curve tools.

XY

Expanding and narrowing outlines

Offset selected points by a set distance. Apply the adjustment in both directions, or only horizontally or vertically, to change the proportions of the selected section.

Symmetry axis and reflection

Set the position and angle of the axis, then reflect the entire outline or selected points. Adjust the point joining distance near the axis to refine the connection between the two sides.

Undoing and redoing changes. Try different outline variations and return to earlier operations while editing.

Refine the appearance of fills and strokes

Set a fill color or gradient, stroke width, and shadow. Choose a solid or dashed line with custom dash and gap lengths. Switch stroke joins between miter, bevel, and round, and line caps between butt, round, and square. Round rectangle corners together or individually.

Example use: draw half an emblem, reflect it across the axis, and refine the curves. Then add a stroke and curved lettering to create your own print motif.

A Product Designer tool

Vectorize images to SVG

Turn a PNG, WebP, or JPEG image into vector artwork. Set the number of colors and level of detail, compare the result with the original, then apply it to the design or download the SVG file.

  • A palette of 1 to 32 colors and an adjustable level of detail.
  • Linked to the source image: you can disable vectorization and recalculate the result.
  • Takes the source mask and filters into account; halftone can remain repeating vector geometry.
  • Processed locally, without using an AI image generation service.

A smaller palette simplifies the artwork's style, while a larger one preserves more color differences. Choose settings that suit your design and review the preview before applying them.

QR codes that fit your design

A QR code can be a consistent part of your product design. Combine a link to instructions, a collection, or your brand website with your own colors, shape, and code element styles.

Alter Product QR code styling example: classic geometry.

Classic geometry

Square elements and a solid color.

Alter Product QR code styling example: soft corners.

Soft corners

Rounded elements, separate frames and centers.

Alter Product QR code styling example: gradient and brand color.

Gradient and brand color

A circular layout, color transition, and independent corner color.

The same alterproduct.com address, with three sets of settings available in the QR tool.

Six dot styles

Give the code a geometric, soft, or decorative character. Combine the style of its inner elements with an independent appearance for the corners.

  • Square
  • Rounded
  • Extra rounded
  • Classy
  • Classy Rounded
  • Dots

Code content and shape

Encode a website, instructions, or collection URL, or your own text. Choose a square or circular shape for the entire code and fit it into the composition.

Separate corner styles

Set the appearance of corner frames and their centers independently. Frames can be square, extra rounded, or circular, and centers can be square or circular. You can also keep the default style.

Four independent color areas

Choose separate colors for dots, corner frames, corner centers, and background. Keep a consistent brand palette or highlight selected parts of the code.

Gradients and precise color values

Use a solid color or a linear or radial gradient. Add color stops, set their positions and opacity, and enter HEX or RGB values. For linear gradients, adjust the transition direction too.

Custom or transparent background

Add a colored or gradient background, or turn it off so the code works with the artwork and product color. Choose a contrast that keeps the code readable.

Space for a logo or motif

Reserve a square, horizontal rectangle, or vertical rectangle in the center. Pair this space with a logo or motif added as a separate design layer.

Scale, rotate, and position the code alongside the other design elements. Before production, check that it scans at the intended print size, especially after changing colors or adding a motif in the center.

Layers, groups, and masks

Keep even complex designs organized. Separate text, images, and decorations, and control their combined visibility with groups and masks.

Order and visibility

Move elements in the layer stack, hide them, and restore them. Build your composition in stages without deleting earlier ideas.

Groups

Combine related elements into a group to manage complex designs more easily.

Masking

Use the bottom layer in your selection as a mask for the others. Limit the artwork's visibility to a chosen shape.

Protecting design elements

Pin fixed elements to the top or bottom of the stack with an owner lock. Keep your logo or other brand elements outside the customer's editing scope while leaving room for personalization.

Your design. Your customer's personal touch.

Personalization for your customers

Offer customers Customizer on your website. In editing mode, they can add text, images, shapes, and QR codes, and refine their composition with a product preview.

As the owner, prepare the design and pin elements that should stay fixed with an owner lock. Editing availability depends on the embedded tool's configuration and permissions. The image vectorization described above is a Product Designer tool.

From your own artwork to a personalized product

Combine image editing, typography, and a 3D preview in one workflow. Prepare the composition, keep control over its fixed elements, and give customers room for their own ideas.
