9. Troubleshooting Guide
9.1. When the Printing Result Is Not as Expected
Depending on the printing conditions, when printing on a dark-colored fabric that involves the formation of
a background with white ink, an undesired printed image may occur.
For problems with printing results, see the solutions below.
When white spot appears
For image types with solid ink, white spot appears on the surface after fixing the ink with a heat press.
Causes:
It may occur when the white ink is not sufficiently dried.
The following causes are possible.
•
The height of the image size being less than 100 mm,* and the drying time of the white ink being
short.
*If the image size is too small, the proper drying time cannot be ensured after the white ink prints.
•
The design of the image uses a lot of dark colors.
•
Large amounts of white ink being ejected. (The intensity is set to 100 instead of the default value of
98.)
•
Color ink flowing when white ink is set to white solid mode (flooding or minimum 100 of brightness).
•
It is set to use a lot of color ink.
Solutions:
Change the print mode on ColorGATE Productionserver.
Select the job in the "Job" archive, and then right-click the selected job.
Click [Settings].
Click the [Color] tab, and then click [Settings] under "Advanced".
Click the [Print Mode] tab.
Select [Brightness - Black Substrate] in [White:] in [Special Colors].
