Print prep software for wall art sellers · Windows

Type the canvas size. Get a print file ready to stretch.

Rassio Forge builds the exact canvas print file from one artwork: wrapped edges, fold and staple marks, hanging points and a DPI check, scaled for your canvas shrink. Triptychs and collages too. Then it batches every poster size you sell.

The problem

Getting art ready for the printer is the job nobody signed up for

One new design should take minutes to print. Instead it eats your evening.

  1. Canvas wraps done by eye

    Bleed, depth and mirror edges measured by hand, one canvas at a time. Get the depth wrong and the image folds over the frame.

  2. Triptychs cut by hand

    Splitting one artwork into 3 panels means guides, maths and three exports, and the gap between panels never lines up on the wall.

  3. Blurry prints found too late

    A 60×90 that looked fine on screen comes back soft. You find out after the print, the frame and the refund.

  4. The framer has to guess

    No fold lines, no staple marks, no hanging points. Every canvas gets measured again at the stretching table.

  5. Canvas shrinks after stretching

    Material pulls a few millimetres and the face comes out short. Fixing it means resizing every file by hand.

  6. Every size, by hand

    One design, ten poster sizes: open, crop, resize, export, repeat. Every new drop multiplies the work.

The fix

One screen replaces the whole evening

By hand

  1. Wraps and bleed measured by hand
  2. DPI checked by guesswork
  3. Panels and collages cut in Photoshop
  4. Framer re-measures every canvas

With Rassio Forge

  1. Wrap, fold and staple marks drawn for you
  2. Effective DPI shown before you print
  3. 7 panel layouts and 7 collage templates
  4. Hanging points and labels on the file

Print prep first, posters too

From one artwork to a print-ready canvas

  1. Step 1: Print prepPro

    Exact canvas sizes, down to the millimetre

    Type the face in mm, the frame depth, the overlap and a back margin for staples and your label. Fill, fit or stretch the artwork, and read the effective DPI with a clear verdict before anything prints.

    Everything the framer needs is on the file

    • Fold and cut lines Fold marks, the cut line and the image edge, plus a TOP arrow so nobody stretches it upside down.
    • Staple marks Evenly spaced staple points on the back margin, at the spacing you set.
    • Hanging points One in the centre, or two at ¼ and ¾, with 1 or 2 screws and the spacing printed beside the mark.
    • Edge labels File name, date, format, DPI, artist credit or the order number, in the top or bottom margin.
    • Your logo on the back Place your logo in the back margin and set its size and opacity.
    • Shrink calibration Canvas pulls when it is stretched. Enter the shrink in X and Y and every file is scaled to match.
    • Up to 1200 DPI Any DPI from 72 to 1200, in TIFF, JPEG, PNG or PDF, saved to a Print Ready folder.
    • Set once, apply to all Save presets, apply one setup to every image, then Export all with Ctrl+Shift+E.

  2. Step 2: Selling posters too? Drop them in

    Then batch every poster size

    57 presets in 7 ratio families, in cm and inches, plus your own sizes. Queue a hundred images, tick what you sell, press Start.

Print prep Pro

For wall art sellers who print, stretch and frame: exact canvases, wraps, panels and collages.

  • Print preview of a canvas with a mirror edge wrap and fold marks

    Five wraps, previewed before you print

    Mirror, solid colour, stretch, average colour or a true image wrap, with a feather that blends the art into the edge. The preview shows the face, the wrap and every fold mark.

  • Multi-panel layout splitting one artwork into three canvas panels

    Triptychs and multi-panel sets

    2, 3, 4 or 5 panels side by side, 2 stacked, 2×2 or 3×3. Set the wall gap and Forge works out each panel and its wrap, so the set lines up on the wall.

  • Collage layout arranging several artworks on one print

    Collages in one file

    Seven templates, from 2 side by side to 1 large + 3 and 3×3. Pick an image per cell or auto-fill in order; each one is cropped to fill its cell, with the gap and gap colour you choose.

For Etsy digital-download sellers

One artwork in, every printable size out

Printable buyers expect every common frame size in the download. Forge cuts the whole set from one file, so a new listing is a queue, not an evening of cropping.

  • 4×6 in
  • 8×10 in
  • 11×14 in
  • 12×16 in
  • 16×20 in
  • 18×24 in

  • artwork_12x16in_crop.jpeg
  • artwork_24x36in_crop.jpeg
  • artwork_A1_crop.pdf

  1. Every ratio from one file

    Tick 2:3, 3:4, 4:5, square and ISO A once. Forge crops one high-resolution artwork to every size, from 4×6 in to 24×36 in and A4 to A0.

  2. A whole collection in one run

    Queue a hundred artworks, tick your sizes and press Start. Forge works through the queue while you write your listings.

  3. 300 DPI on every file

    Each size is saved at 300 DPI, in JPEG, PNG, TIFF or PDF, ready for a home printer or a print shop.

  4. Names buyers understand

    A file-name template puts the size in every name, so a buyer finds 16×20 in without opening each file.

  5. One folder per artwork

    Save to one folder, or one folder per image, ready to upload to your listing or behind the link in your download PDF.

  6. Your designs stay private

    Everything runs on your own PC. Nothing is uploaded, so unreleased designs stay yours.

FAQ

Questions before you start

How do I get the app after I pay?

Within a minute you receive an email with your login. Set a password, open your account, download the installer and copy your licence key. Paste the key into the app and you are ready.

Automation or Pro — which one do I need?

Automation exports every ratio and size you sell from one batch. Pro adds Print Prep: one exact size with a DPI check, multi-panel splits and collages, and a print preview with the wrap. If you print, frame or sell canvas yourself, take Pro.

I already use Photoshop actions. Why switch?

Keep them if they work for you. An action resizes; Forge builds the canvas file from your measurements: the face in mm and the frame depth, the wrap, fold, staple and hanging marks, shrink calibration, and triptychs split with the wall gap. Photoshop doesn’t need to be open. Run 10 of your own images through the free trial and compare.

My print partner already wraps the canvas. Do I need Pro?

Probably not. If a lab or print-on-demand service does the wrap, the Automation edition covers what you need: every poster and printable size from one batch. Pro is for sellers who print, stretch or frame canvases themselves.

How many computers can I use?

One computer at a time. Changing PC? Deactivate the old one from your account, then activate the new one in one click.

How does the yearly plan give 3 months free?

A yearly plan costs 9 times the monthly price, so you pay for 9 months and get 12.

What is the Lifetime licence?

One payment of $299 for the Pro edition, including every future update. No renewal, ever.

Can I get a refund?

Yes. If Rassio Forge is not right for you, email us within 30 days of your first payment and we refund you in full.

Is there a free trial?

Yes. Download the app and process up to 10 images free — no card needed.

Does it upload my files anywhere?

Never. Everything runs on your PC, so your artwork never touches a server. The app only goes online to check your licence, and it keeps working offline for up to a week.

Which computers does it run on?

Windows 10 and 11, 64-bit. It is a standalone app: no Python, no plugins, nothing else to install.

Which sizes and formats are included?

57 presets in 7 families (square, 2:3, 3:4, 4:5, ISO A, 3:2 and 2:1) in centimetres and inches, plus your own sizes in cm, inches or pixels. It reads JPG, PNG, TIFF, BMP, WebP and PSD, and writes TIFF, PNG, JPEG or PDF at 300 DPI.

What happens if I cancel a plan?

Every file you made stays yours. The app stops processing new batches at the end of the period you paid for, until you renew.

Run your next canvas through Forge. 10 images free, no card.

Every feature works in the trial, on your own PC. Nothing is uploaded and there is nothing to cancel.
