Upload artwork → we split it per ink and convert it into printable dot rasters → download your films. In your browser. No RIP, no Photoshop.
Spot colors, or Pro CMYK process separation (beta). 4 fixed-angle inks, no ICC color management. For fully colour-managed photorealistic process work, use a pro RIP.
Each ink is clustered from your artwork’s colors and screened separately.
What happens to your imagecolours → inks → printable dots
1. Your artwork — colors and smooth shades, straight from JPEG or PNG.2. Split into inks — one layer per color. Each layer gets its own screen.3. Converted into dots (the raster) — a press prints ink or no ink, nothing in between. Shades become bigger and smaller dots, like newspaper print — or choose solid instead of dots (for lino / block printing) in step 3. This is what goes on your film.
Union of every ink, choked inward so registration drift never shows white at the edge.
4 fixed process films · C 20° · M 80° · Y 65° · K 50° · elliptical dot
No color management (ICC). This is a basic RGB→CMYK separation with a fixed, conservative ink limit — for accurate, colour-managed photorealistic process work, use a calibrated RIP.

Print setup
A knit swallows small dots and gains 15–35%, so dots stay coarser and the tonal range is clipped harder.
Dots below the clip floor fall through the mesh; above the ceiling they bridge. Clipping is intentional.
Height follows the artwork ratio. Wider than 18″ (457 mm)? The sheet is cut into panels automatically (Pro).

Extras (Pro)
Tick one to show its settings. The preview is free; generating needs Pro.
Bigger than one film can be, or bigger than your printer? Pick your paper size and the sheet is cut into overlapping, numbered panels with join marks. The halftone screen runs on across panels. Print widths above 18″ (457 mm) and panels are Pro; the summary below is free.
Turn your artwork into one seamless sheet: the artwork is one tile, and every film covers the whole sheet. The halftone screen runs on unbroken across tile edges, so the screen itself never shows a seam. It works for screen printing (halftone dots) and for relief and lino (solid shapes, with kento marks). The preview is free; the tiled films need Pro.
Wallpaper and fabric are ordered by sheet or roll width: enter it and the tile width is worked out for you.
Blank paper between the tiles, in the unit chosen above (mm or inch). 0 = tiles butt. A negative value makes the tiles overlap and their ink merges.
Repeat ticks in the margin
A small mark at every tile edge along the bottom and left margin, to check the repeat on press.

Registration: getting every layer to land in the same place
Every colour after the first has to land in the same place. Two approaches, both older than any of us:
A registration jig.A board with a right angle for the block and another for the paper, so both drop into the same position every time. Cheap to build from scrap and accurate enough for most work.
Kento marks.The Japanese moku hanga method: a corner notch and an edge notch cut into the block itself, into which the paper is seated. Elegant, and it travels with the block.
The registration marks and crop ticks printed in the margin of each layer give you a common reference across all of them — align the marks, and the layers align.
Pro removes every limit: unlimited inks, 720 dpi output, no FREE mark in the margin, and as many jobs as you like. The free version stays free for trying things out.
Film thumbnails show moiré from screen scaling — the downloaded file is clean 1-bit. Ink density on film depends on your printer driver settings, not on this file.
