Troubleshooting black and color output from EasySIGN

Audience

This article is for EasySIGN users who print from EasySIGN and notice that black or other colors do not print as expected.

Primary use cases

Use this article when:

• Black prints with a blue, green, or other color cast.

• RGB black does not produce the expected matte black result.

• The printed result differs from the color shown in EasySIGN.

• You print through RIP software such as VersaWorks.

• You send print jobs from EasySIGN through a TPR workflow.

• You want to choose between matte black and rich or glossy black.

Customer scenario

A user creates artwork in EasySIGN and sends it to a printer or RIP workflow.

The artwork contains black objects. On screen, the black may look correct, but after printing it may have a blue cast or may not look like the desired matte black.

This can happen when RGB black is interpreted or converted by the RIP, printer driver, color management settings, or ICC profiles.

Summary

For matte black, use:

• CMYK 0,0,0,100

For rich black or glossy black, use:

• CMYK 100,100,100,100

Avoid relying on RGB 0,0,0 when you need predictable printed black. Depending on color management, RIP settings, and ICC profiles, RGB black may be converted into a composite black that can show a color cast.

1. Purpose and scope

This article explains what to check when black or other colors print differently than expected from EasySIGN.

It covers:

• Choosing CMYK black for matte black.

• Choosing rich black or glossy black.

• Understanding why RGB black can give unexpected printed results.

• Checking RIP, color management, and ICC profile settings.

• Testing output before production.

This article gives practical print-color troubleshooting guidance. It does not replace printer manufacturer documentation, RIP documentation, media profiling, or professional color management setup.

2. Symptoms or customer problem

You may see one or more of the following symptoms:

• Black prints with a blue cast.

• Black prints with a color tint instead of neutral black.

• Matte black is expected, but the print looks different.

• The print result does not match the EasySIGN screen preview.

• The same artwork looks different in the RIP.

• The issue occurs after sending the file to VersaWorks or another RIP.

• The result depends on color management or ICC profile settings.

3. Cause or background

There are different ways to define black in design and print workflows.

RGB black is commonly defined as:

• RGB 0,0,0

This may look black on screen, but the print result depends on how the RIP, printer driver, color management, and ICC profiles convert RGB values to printer ink values.

For print workflows, black is often more predictable when defined directly in CMYK.

CMYK black for matte black is:

• CMYK 0,0,0,100

Rich black or glossy black is:

• CMYK 100,100,100,100

The final printed result can still depend on:

• RIP settings.

• Printer settings.

• Media type.

• ICC profiles.

• Color management settings.

• Ink configuration.

• Print mode.

4. Solution

Use the correct color definition for the required print result.

For matte black, use:

• CMYK 0,0,0,100

For rich black or glossy black, use:

• CMYK 100,100,100,100

Then check the RIP and color management settings before production.

5. Step-by-step procedure

Step 1: Check the black object in EasySIGN

1. Open the EasySIGN worksheet.
2. Select the object that should print black.
3. Check whether the object is defined as RGB or CMYK.
4. If the object uses RGB 0,0,0, change it when a more predictable printed black is required.

Step 2: Choose the correct black value

1. For matte black, set the color to CMYK 0,0,0,100.
2. For rich black or glossy black, set the color to CMYK 100,100,100,100.
3. Apply the color to the required objects.
4. Save the EasySIGN worksheet.

Step 3: Check the RIP or print workflow

1. Send the job to the RIP or printer workflow.
2. Check the preview in the RIP software if available.
3. Confirm that the intended color mode and profile are used.
4. Check whether the RIP applies color management or automatic color conversion.
5. Check whether the correct media profile or ICC profile is selected.

Step 4: Run a small test print

1. Print a small test sample before full production.
2. Compare the printed black to the expected result.
3. If the black still has a color cast, check the RIP color management and ICC profile settings.
4. Adjust the workflow if needed.
5. Repeat the test before printing the full job.

Step 5: Check other colors if needed

1. If other colors also print differently than expected, check whether they are RGB or CMYK.
2. Check the color management settings in the RIP.
3. Check whether the correct ICC profile is used for the media and print mode.
4. Run a test print before production.

6. Validation

The issue is solved when:

• Matte black prints as expected using CMYK 0,0,0,100.

• Rich black or glossy black prints as expected using CMYK 100,100,100,100.

• The print no longer has an unwanted blue or color cast.

• The RIP preview and output workflow have been checked.

• The correct media and ICC profile settings are used.

• A small test print confirms the expected result before full production.

7. Important notes and limitations

• RGB 0,0,0 can print with a color cast depending on conversion settings.

• For matte black, use CMYK 0,0,0,100.

• For rich black or glossy black, use CMYK 100,100,100,100.

• The final printed result also depends on the RIP, printer, media, ICC profiles, and color management settings.

• EasySIGN can define the design color, but the printer and RIP determine how that color is converted to ink.

• Always run a test print when color accuracy is important.

• For advanced color accuracy, check the printer manufacturer, RIP documentation, media profiles, and ICC color management setup.

8. Support checklist

Before escalating the case, check:

• Which color value is used in EasySIGN?

• Is the black object defined as RGB or CMYK?

• Is the user using RGB 0,0,0?

• Does the user need matte black?

• Has CMYK 0,0,0,100 been tested?

• Does the user need rich black or glossy black?

• Has CMYK 100,100,100,100 been tested?

• Which RIP or print workflow is used?

• Are color management settings enabled in the RIP?

• Is the correct ICC profile selected?

• Is the correct media profile selected?

• Has a small test print been made?

• Does the color issue occur with all files or only one file?

9. Conclusion

When black prints with a blue cast or does not appear as the expected matte black, check how the black is defined in EasySIGN.

For matte black, use CMYK 0,0,0,100.

For rich black or glossy black, use CMYK 100,100,100,100.

If the output still differs from the expected result, check RIP settings, color management, media profiles, and ICC profiles, then run a small test print before production.
