How it works

Load. Tune. Export.

01

Load your artwork

Drop in a PNG, JPG or SVG, then set the print size in centimeters and the output DPI.

02

Choose a print method

DTF, single ink or separation. Pick a mesh and ink preset, then let Auto tone set the curve as a starting point.

03

Export films

Download print-ready PNG at your DPI, or a ZIP with one film per ink and registration marks.

Features

Made for the way shirts get printed.

Three print methods

DTF, single ink for screen printing, and separation into one film per ink. Switch method without reloading your artwork.

Dots, diffusion, threshold

Round, elliptical, square, diamond or line dots with adjustable angle and LPI. Or diffusion for fine grain, or a clean threshold.

Presets, Auto tone, calibration

Mesh and ink presets for DTF, plastisol and water-based. Auto tone sets the curve, and the calibration strip tests your dot gain on press.

Background and color knockout

Remove a solid background in single ink, or knock out one color for DTF, with tolerance and fade.

Ink separation

Detect 2 to 8 ink colors, edit them, and export one film per ink. Add a white underbase with choke, and mirror the film if you need to.

Print-ready export

PNG with DPI metadata (300 DPI), registration marks, and a ZIP of films. Warnings flag low source resolution, tiny cells and high LPI.

FAQ

Good to know.

Which printing methods does it cover?

DTF, single-ink screen printing, and separation into one film per ink. Each has its own settings, so you only see what applies.

Are the mesh and ink presets calibrated?

They are starting points based on common rules of thumb, such as mesh being roughly 4 to 5 times the LPI. Use the calibration strip to test dot gain on your own press and save the result as your own preset.

Do I need an internet connection?

No. LaRastra is a single HTML file. Once you've downloaded it, it runs offline in your browser.

Is my artwork uploaded anywhere?

No. Everything is processed on your own device. Nothing is sent to a server.

Can I use the results for client work?

Yes. You can use everything you create in client work and commercial products, with no attribution. The license covers one person, and the app itself can't be resold or shared. Read the full license →

How do updates and refunds work?

Updates within version 1.x are free (details). If the app doesn't work as described and we can't fix it, you can ask for a refund within 7 days (refund terms).
