I am opening the public beta of calc ICC

A professional ICC color conversion calculator for iPhone and iPad.

The idea behind calc ICC is simple: make serious color calculations available wherever you are, without requiring a desktop workstation. It is designed for designers, prepress operators, photographers, color professionals, and anyone who needs to inspect or convert color values using real ICC profiles.

What calc ICC can do

The app supports:

• Input, output, proofing, DeviceLink, and named-color ICC profiles
• RGB, CMYK, Lab, and multichannel color spaces, including ECG workflows with up to 15 channels
• Color conversion using standard rendering intents and black point compensation
• Soft proofing and gamut checking
• CMYK-to-CMYK conversion while keeping the ink formula for the same Lab color
• Fast numerical entry designed for practical color work on a mobile device

This is not intended to replace a complete prepress workstation. It is a focused tool for answering color questions quickly and accurately when an iPhone or iPad is the most convenient device at hand.

Why a public beta

Color workflows are varied, and ICC profiles found in the real world are often more interesting than the carefully prepared files used during development. I would like testers to use calc ICC with their own profiles and actual work. In particular, I am interested in anything that seems unclear, slow, incorrect, or unexpectedly difficult. Reports involving unusual profiles, multichannel data, DeviceLinks, named colors, proofing, and gamut checks are especially useful.

The beta is free, but the number of installations is limited and places are available on a first-come, first-served basis.

Thank you for testing calc ICC. Careful feedback from people who actually work with color is what will make the final release better.
