Suggestions for print stencil in high quality
The printing process is thermal, the image is transferred to paper by the
heat of the print head, so:
• Cool the print head (5/10 minutes) between a stencil and another
one (keep printing indeed will get worse outcome).
• Always remember: darker image = higher temperature.
• If the heat of the print head rises too high there is the risk of rippling
and crumple the paper. The stencil can be damaged (vertical lines
due to wrinkles appear on the paper) or even paper can jam in the
printer.
• Print a stencil at once. You will get better results. The paper can be
reused to print a new stencil, just choose a new position for the new
image.
• Clean the print area (print head and roll) with compressed air.
Compressed air also allows you to better cooling down the print
head.
• Use latex gloves for handling the paper.
