Rebuild an ink colour exactly, months after you first mixed it.

Royal Casino stores every mix 🥣 as parts plus the grams you actually weighed on the slab, so the recipe scales to any sheet count instead of sitting in a notebook as a colour name. Add bases, drag ✋ the live parts bar, and lock the mix when it matches.

Pull a draw-down on the stock you are actually printing, photograph the swatch, and tag its tack and opacity. The same mix 🥣 reads differently on cotton and coated paper, so every swatch is bound to a named paper stock and the recipe compares them side by side.

Each tweak toward the target 🎯 is logged as a correction step with its delta and note 📝, so the path to a colour is reusable, not just the endpoint. Bind a locked mix 🥣 to a press run, record the leftover ink returned to the can, and see 👀 consumption accumulate per base on the inventory gauge.

A starter set of common letterpress bases and modifiers — transparent white, tint base, driers — ships with the app 📱, each with its tack and opacity handling notes 📝, so the bench is useful on first launch.

Everything runs on your device 📱 against a local database. There is no account, no sign-up and no connection required for any part of the workflow, including the camera 📷 capture of a draw-down and the gallery 🖼️ import 📥 of a colour reference.

What you can do in Royal Casino:
- Mix 🥣 by parts and grams on the slab, then lock the recipe
- Rescale a locked recipe to a new ✨ sheet count and paper stock
- Capture draw-downs on real stock and tag tack and opacity
- Keep the ordered correction path toward a target 🎯 colour
- Log 📝 press runs with sheets printed, grams mixed and leftover returned
- Track per-can consumption across your ink bases

Start 🚀 your next mix 🥣 on the bench and keep the recipe.
