Separation software for screen printers
Separations, reinvented for screen printers.
Open any art and get one film per ink, sized and ready for your film printer. Every dot belongs to one ink, so no ink lands on another.

What's new
October 2026.
Clean dots
Paper grain, scan noise and JPEG mush finer than one dot are smoothed out, so tones print as round dots of steady size. Lines and edges stay sharp.
On for every Index job.No ring dots
Where three inks share a spot, the smallest prints as its own dots between the others, never as a ring around another ink's dot.
Every film holds whole dots only.Smallest dot fade
Below the smallest dot your mesh holds, a color prints as fewer dots of that size instead of stopping at a hard line.
Set it under Dot limits.JPEG cleanup
Color blocks from JPEG compression are smoothed when the art loads. Brightness and real color edges are left alone.
Runs on every file.Key colors
The ink picker keeps small key colors, like a red logo, instead of spending the count on shades of the big ones.
Swap or eyedrop any ink after.1 to 12 inks
Ask for any count from 1 to 12. Index starts at 6, and the count you pick stays when you re-pick.
Solid picks its own count.Cleaner films. Every dot on a film is one ink, whole and round, and nothing is smaller than your mesh can hold.

FAQ
What files can I open?
Image files like PNG and JPG, and PDFs. Small or compressed files are fine. They're enlarged to 300 ppi when they load, and JPEG color blocks are smoothed before separating.
Do I need Photoshop?
No. RipIT runs in the browser. It picks the inks, makes the films and lays them out on your sheet with registration marks.
What film printer do I need?
Any of the usual ones: an Epson inkjet at 720 or 1440 dpi, a laser film printer at 600 or 1200 dpi, or an imagesetter at 2400 dpi. Pick yours and the films are made at its resolution, with setup tips for printing without a RIP.
Which method should I use?
Index for shading, painted and photographic art: inks sit side by side as dots. Solid for flat art like logos and lettering: every spot prints one full ink with no dots.
Can I change the inks it picks?
Yes. Set the count from 1 to 12, swap any ink, or pick a color straight from the art. Inks you've edited keep their settings when you re-pick.
