Below is a compilation of our most common settings. A lot of settings are Anatol Volt specific because of their collaboration with us and the fact the the electric Volt is a superior machine for consistant squeegee down pressure. The new Volt has digital downpressure which should make it even better!
With that said we have partners set up on M&R, ROQ, Workhorse, MHM and many others with the Riso system.
Offset
Print Platen Offset 3-5mm (1/8” -3/16”). Anatol position for standard printing is 5 (.05)
Squeegee
Speed – 20 Best performance for thicker inks can go 30+ for Color Inks.
Durometer
White Ink – 60 or 60/90/60
Color Ink – 70
Angle
White 25-30
Colors 15-20
Flood
The pressure adjustment system on VOLT is just a dial adjustment manually.
Just touch squeegee blade on the platen and increase quarter or half round of the dial adjustment or maybe 2 marks of the pressure height measure on the equipment.
There are also flood blade pressure adjustment as well. Flood blade does not need to touch on the screen. 1mm gap with screen should be OK.
Pressure
Roughly 1/3 to ½ of conventional downforce. (M&R is set at 60-65 lbs, ours works at 20-38 lbs)
Extra notes
***Extremely critical***
The parallelism between the screen and platen are critical for consistency. Make sure the squeegee blade, frame and platen are parallel to each other,Make sure the squeegee is perfectly square to the platen. if it is uneven, it will cause a premature screen failure on one side.
The tension of the screen can be anywhere from 15-20 N/m (not so critical) but the difference at 90 degree angles should be within +/- 1 N/m (important). We are measuring with a standard tension meter.
Like conventional mesh our mesh will give over a period of time. Make sure to watch our videos on YouTube regarding stretching using the quick frames so you can force relax the mesh to make your screens. The video will show you how to do the 2 step process faster than waiting on the screens to relax.
If you have any lint balls on the platen clean them as they can cause pinholes.
Make sure that you flash just after you print to allow it to cool before the next print station. If you plan to use a flashback you will need a fan on it between the print and flash. Most of our customers just print a full rotation, it allows the platens to cool.
If you see banding occur after a print it may be that the thermal head is not heating up enough to burn properly or most likely the area it is being used in is too cool. The recommend operating temp of mesh and QS is 72-82F. We can turn up the thermal head heat in cases where the shop temp is too low.
Tips for more white ink
Use Xpressmagic to open the screen area up and the screen and screen hardener to improve durability.
Add a white neutral base to the white at about at a ratio of 1:3 to get a lower viscosity.
I want to thank Joe Ocampo at Fully Promoted in Escondido, CA. Most of these notes are his and he has been invaluable as a source of good information for our partners!
