If you’re reviewing images in Ziflow and notice that colors don’t match the original file, the issue is usually related to how web browsers handle CMYK color profiles. This article explains why it happens and how you can adjust Ziflow settings to ensure consistent color display.

Why this happens

Many images intended for print use the CMYK color profile. However, web browsers are optimized for RGB color, and they don’t all handle CMYK the same way:

• Firefox: Generally displays CMYK colors correctly.
• Chrome (and some other browsers): May display CMYK images with inaccurate colors.

If you drop the same CMYK JPEG into Chrome and Firefox, you’ll see the difference.

How Ziflow displays images

By default, Ziflow loads the original image file in the Proof Viewer if it’s under 10 MB. This means:

• If the file is a CMYK JPEG and you open it in Chrome, you may see a color shift.
• If you open the same proof in Firefox, the colors will appear correctly.

Note: This behavior only affects CMYK JPEGs. RGB JPEGs, PNGs, and other formats display consistently across browsers.

Fixing color display issues

If you want Ziflow to handle the processing so that images display consistently in any browser, you can change a Proof Viewer setting.

1. Go to Settings > Proofing Settings > Proof Viewer > Other Options.
2. Find Show original image.
3. Change the setting to Always process.

When enabled, Ziflow will process (tile) newly uploaded images so they display correctly across browsers.

Important: This setting applies only to proofs uploaded after the change. Existing proofs will need to be re-uploaded.

Other options

• Use Firefox: If you don’t want to adjust your settings, open proofs in Firefox to view CMYK colors correctly.
• Convert to RGB before upload: If possible, save your files in RGB color mode, which is optimized for web display.
