Guidelines for printing fabrics
on Roland solvent printers

Please note this information is based on our Roland VersaCAMM VS-640 and may differ from other Roland models.

PINCH WHEELS:

We recommend you use all pinch wheels where possible, this will help prevent the media lifting whilst advancing through the printer.

EDGE GUARDS:

Use edge guards where possible; in particular on soft lightweight fabrics.

This photo shows the Roland VS-640 solvent printer control panel and the print operators hand pressing the ENTER button as the display shows the CLEANING, TEST PRINT function is selected.TEST DRAW:

We recommend performing a "TEST DRAW" on the printer. This will show you whether all of the nozzles are firing correctly.
On the front panel select:
FUNCTION
/ CLEANING / TEST PRINT

This will print a colour patch – if there are no obvious breaks in the pattern then the nozzles are fine.

Running machines with missing nozzles can be OK; however missing colours in the output can look unsightly and lead to work being rejected by your client!

The image below shows a print head nozzle test with missing and/or wavy lines which can result in poorer print quality, while the diagram below this shows a perfect example of well kept printing heads.

Print head nozzle check test print: top: nozzles missing which may result in poorer quality prints and BOTTOM: a perfect print head nozzle test showing no missing lines means a well kept set of printing heads.

FEED DIRECTION CALIBRATION:

For printers that use the "Intelligent Pass Control" this isn't so critical (but advised).
Earlier models that don't have this, it is essential that you perform this calibration on your printer.
Feed Direction Calibration is crucial to prevent horizontal banding.
Follow the following guidelines to set this up...

Perform the position correction of feed direction (alleviate horizontal stripes)
NOTE: Feed direction means the feed direction of the media/material you are using. Perform the correction adjusting to the media in advance because horizontal stripes are more likely to occur during printing when the movement distance of the media changes subtly depending on the media's thickness.

This graphic shows the group of functions you will need to select in the order as described on your Roland VS-640 solvent printer control panel to perform the position correction of materials feed direction through the printer.

Tensioning:

Use tension bars where possible.
Following these guidelines and using our profiles where available, will help in achieving good printing results.
