Eliminate pinholes by masking outside areas of the screen. Screen Masking Tape is used with both Screen Printing & PRINT GOCCO Masters.
Using Screen Masking Tape
Screen masking Tape is used
to eliminate pinholes/ tiny dots/ marks (pictured right) that appear on
your screen.
Leaving a 2 cm. wide border around the outside of the design, cover the open areas of the Screen with Screen Masking Tape. Attach the tape to the film (smooth) side of the ScreenMaster as pictured left.

When pinholes are too close to the design, mask the screen with Screen Masking Tape and then use RISO Correction fluid for the areas close to the design as shown right.

Never before has screen printing been so fast and easy, in fact no screen printing experience is necessary to begin making screens!
In our newsletters we often explain Screen Printing applications and ‘how to . .’ information, but why is RISO such a great Screen Printing system and what equipment do you need to start Screen Printing?
RISO Screen Printing gives you:
Traditional photochemical emulsion and hand cut stencils are costly and very time consuming processes to make a screen. They require knowledge of screen making and generally about 24 hours to make a screen, with often hit and miss results.
With RISO all these age old problems are eliminated and an easier way of Screen Printing is available.
RISO Screen Printing Kit Makes Screen printing Easy
All 5 elements above are now available in a single kit, with an imaging machine (PG-5 model), RISO ScreenMaster, Frames, Squeegee, Ink & easy to understand instructions to get you going instantly!

Plastics & metals are a non-absorbent material, so when we print them the ink sits on top of the item and then cures/ bonds as it dries, unlike fabric inks which are absorbed. This means we can not have the screen directly on top of the item or the ink will smudge / blur when we lift the screen.
We easily get around this problem by elevating the screen slightly above the item and then printing, this process is called ‘off contact’ printing - you may have heard us mention this before.
We also need to use a finer grade mesh then the normal 70Mesh, used for fabric screen printing, to eliminate the ‘mesh mark’ caused by the inks not being absorbed. The PRINT GOCCO B6 & B5 Print Masters are an ultra fine 200Mesh and can be used for screen printing in short run applications (up to about 500 prints).
A simple guide on how to use B6 & B5 Print Masters to print plastic & metals.
Materials Required
B6 Print Masters (code: S-489) or B5 Print Masters (code: S-180)
Imaging system - RISO Screen Printing Kit, RISO Ceramic Printing Kit or PRINT GOCCO model (PG-5, PG-11, PG Arts, B6, B5, etc.)
Long Life Squeegee - 110mm for B6 Print Masters or 170mm for B5 Print Masters
Plastic Frame Mounts - 3 x Small for B6 Print Master or 5 x Large for B5 Print Masters
RISO Aqua Ink for Plastics/ Metals
Step 1 - Imaging your Print Master/Screen
Prepare your artwork for imaging by eliminating any moisture and excess carbon from the design. Use the Artwork Clean-Up Process before imaging your artwork.
Imaging your Print Master for screen printing is exactly the same as for Paper/ Card printing - instructions are detailed in your Operation Manual or on separate Information Sheets in the TRAINING section of the site.
Step 2 - Mounting your Print Master to a Frame
After
imaging your design onto your Print Master, remove it from the machine
Tear the plastic flap from the Print Master, as pictured right, as this is not used when screen printing with the Print Master
Prepare the plastic frame by remove the protective coating of the double sided tape along the two long edges of the plastic frame. Leave the tape on the two short edges of the plastic frame.

Place your Print Master onto the plastic frame with film side in contact with the double sided tape - cardboard facing upwards, pictured left.
Your Print Master is now attached to the plastic frame by the long sides of the frame. You will note the Print Master is slightly shorter than the frame - this is why we leave the double sided tape on the short sides.
Step 3 - Elevating the screen for 'off contact' printing
As the screen must be elevated for printing, the printable area of the screen decreases the higher we elevate - we cant print right to the very edges without tearing the screen!
As we are using B6 and B5 Print Masters the maximum size we can print is almost the same each time.
A B6 Print Master (100x150mm) elevated with 3 frames give us 50mm x 90mm print size
A B5 Print Master (165x235mm) elevated with 4 frames give us 110mm x 150mm print size
We elevate the B5 Print Master slightly higher as the larger the screen size the higher we need to elevate to stop the middle of the design ‘sticking’ when printed.
Place
the additional plastic frames under the attached screen and test the height,
pictured right. We are trying to elevate
the screen as high as possible above the item BEFORE the edges are not able to
touch the item below.
How hard should you press to test? You should be able to gently press down over the design area with your finger and the screen will come in contact with the item.
If you are pressing too hard you may stretch/ tear the screen. There is no need for hard pressure - use the squeegee if you are unsure and simply perform a dry print (instead of using your finger to test).
If the edges do not come in contact with the item below then remove a plastic frame.
If the edges easily touch the item add another frame and re-test
Remember, you can always increase/ decrease the height of the screen after you begin printing, as you use the straight edges of the frames for your registration (covered below) so changing height is fast & easy.
Step 4 - Printing your design
By now you should have the Plastic Frames and Print Master stuck together and set to the correct height for printing.
The actual printing process is the same as for screen printing plastics, excepting you use RISO Aqua Ink. Do not use extra pressure on the squeegee when printing - the screen will naturally lower to the item when printing
The final step is to register the print over the item, this best done using a NEHOC Screen Printing Jig (S-360) - or set of Jig Hinges (S-360H).
Depending upon the item you are printing, you can also set up some simple guides on a table, etc. - this often the fastest, and of course cheapest, method if only a few prints are required.
