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.
We recommend you use all pinch wheels where possible, this will help prevent the media lifting whilst advancing through the printer.
Use edge guards where possible; in particular on soft lightweight fabrics.
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.
Feed Direction Calibration
For printers that use the “Intelligent Pass Control” this isn’t so critical (but advised). For 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.
Use tension bars where possible.
Following these guidelines and using our profiles where available, will help in achieving good printing results.
