with CorelDRAW and Summa's Color Control & Printer Control.
The biggest complaint with Summa’s Thermal Printers
is the excessive banding. I hear it constantly, and almost always it's an inexperienced user and or incompatible vinyl.
Some common causes and a solution.
The submitted print ( from this thread ) yup it’s bad...a bunch of things right off the bat
DUST, DEBRIS, CONTAMINATION & PRINT PASS ALIGNMENT. You also notice different
shades or "shifts" in color on each pass of the print head - we will correct 90% this with a linefeed calibration.



Let’s calibrate the linefeed - at the printers console
“Printer Menu” > “Calibrate Linefeed” > Choose 2 “Recommended”
With Clean Media, I print again ” cmy” “default screens”, still slight banding in the
face. ehh

OK lets go back to CorelDRAW, Select your image and go > Bitmaps > Add Noise

I like to sample the real problem area’s, here I choose a medium part of the face.
set level to 50 and density to 50. You probably can get away with less, but time is money.....

I also go into Summa Printer Control and change Colorshift from Standard to HIGH
I then send it to Color Control and leaving the screen freq. alone (55) and change shape to "rhomboid" and print in CMY
The final result......
