Inkwell pad printer, pad printing making package
Ink Well pad printer making package:
20 photopolymer plates ( 75mm x 100mm)
50 A4 size Transparent films ( for injet printer or laser priter uses )
Open ink well systems use a trough (ink well) for the ink supply, located behind the printing plate. A flood bar pushes a pool of ink over the plate, and a doctor blade removes the ink from the plate surface, leaving ink on the etched artwork area ready for the pad to pick up.
AD:blade is very cheap, waste ink,
Sealed ink cup systems employ a sealed container (ink cup), which acts as the ink supply, flood bar and doctor blade all in one. A ceramic ring with a highly polished working edge provides the seal against the printing plate.
AD: ceramic ring is expensive, save ink.
1:Pad Printer (Inkwell) ONE Unit
Size: 75mm x 100 mm(for our ink well pad printer )
4:Transparent films: 20 SHEETS
( for ink-jet printer or laser priter uses )
Polymer plates Pad Printing Plate Making Process
Remove cover film slowly and place positive film onto undeveloped plate.
Use positive film having optical density of not less than 3.0.
Expose plate, through positive film, to UV light having 360 nm wave lengths for 1-2 minutes.
Remove positive film and place screen film on undeveloped plate.
240 and 300 lpi screen films are available and are supplied by our distributor in your country.
Expose plate, through screen film, to UV light having 360 nm wave lengths, for 5-6 minutes.
Give longer exposure time, if shallower cell depth is required.
If wash out unit is not available, you can wash it out with running tap water.
Expose the dried plate to UV light again for 5-10 minutes in order to get stability.
1. Gloss film as well as matted film can be used.
2. Good contact between film and plate is essential.
3. Treat films carefully as any kink will be reproduced on the developed plate.
4. Check film and plate without any dust before exposure.
5. Minimize the pressure of doctor blade to enjoy longer durability of plate.
6. It can be used in inkwell system and closed ink cup system.
Important notes about making printing plates:
* The first exposure time on the film positive determines the overall depth of the ink well. The SHORTER the exposure time the deeper the printing plate.
* The second exposure on the film positive determines the amount of ink, the size of the dot and the spacing between the dots.
* Reducing the 2nd exposure time on the screen will reduce the height of the dot and will let more ink transfer
* You can control the printing effects by varying halftone screens:
