RISO ScreenMaster
Can the ScreenMaster mesh be re-used after a design has been imaged onto it?
How detailed can the artwork get?
Once a screen is created, how many prints will I get before the quality lessens?
Can I clean the screens and use them again as many times as I want?
Each time I use a mesh stencil  . . . . do I have to clean it with a solution?

'Can the ScreenMaster mesh be re-used after a design has been imaged onto it? if so, how many times? how do you clean them and/or care for them to get longer use?'

The design can not be taken off the screen and the actual mesh re-used like traditional silk mesh, however the screen can be removed from the frame, stored and re-used later.
This gives you the added benefit over traditional silk in that your costs for creating the screen are not then wasted if you have to reuse the screen for a different design.
Screens are cleaned in cold tap water and then dry naturally. You can store them on the frame, off the frame rolled up or off the frame stored flat [in a folder]

How detailed can the artwork get? how does it handle lettering?
 
RISO ScreenMaster 70Mesh will image 6pt type and 1pt lines, plus half tones. 
Fine quality is not an issue as you can't go too fine onto fabrics as you will lose the design in the weave of the fabric.
Personally I don't like going below 14pt type as it just is too small and no one can read it from any distance - not many people get that up close and personal with your t-shirt!

'Once a screen is created, how many prints will I get before the quality lessens?'
Each screen is designed o last about 1,000 prints, however this will vary upon the surface you are printing.
If you use a rough calico material then you will receive about 700-900 prints.
BUT I have personally printed 4,500 pieces of cotton with a single screen [that's a lot of prints!!!].
 
When the 'quality lessons' it normally means the film on the back of the screen begins to break.
You can also prolong this by using Screen Masking Tape applied to the back of the screen BEFORE printing starts.
Using Screen Masking Tape you can increase your prints on rough materials by 20%-50%.

'Can I clean the screens and use them again as many times as I want?'
Yes screens are easily cleaned and stored for later use.
You can either leave the screen on the frame or take it off and reuse the frame, storing the screen in a folder [or in a tube]. This means if you only print 200, you can store it and print another 200 next week/ month/ year.
 
Screens will store indefinitely as long as they are stored correctly - away from heat.

Another enquiry is cleaning solutions. I've never screen printed before. So each time I use a mesh stencil and set it up for a new shirt, do I have to clean it with a solution? If so is the solution environmentally friendly...as in if I'm in a hurry can I just toss it out my garage window into the garden without frying plants and flowers?

No, no, no - we don't touch ANY solvents or chemicals with this process, in either making the screen or cleaning.
 
The ScreenMaster mesh is supplied with the thermal film already coated on the back of the screen.
When we image the screen we burn away the film to expose the design.
 
When we have finished with the screen you can not get rid of the design, but you can of course clean it and store it for later use.
The advantage we have is you can take the screen on/off the frame so you can reuse the frame for another screen.
Inks are all water based so everything is just washed up in cold water in the sink - no hi-pressure hosing or washouts.
 
If you are in a hurry you clean the excess ink off the screen and throw the frame into a tub of water [where it can sit for ages] and this will stop the ink from drying in the holes and blocking the screen. If you are in a hurry and don't want the screen again then  of course just bin it.
