SEALED CARTRIDGE
The ink is stored inside a glass. This cup has a blade and acts as an inkwell, spreader and scraper.
BENEFITS
-
Lower Evaporation of Solvents;
-
Faster setup;
-
You need less knowledge to adjust the machine;
-
Greater solvent/ink stability;
-
Less vulnerable to dust and environmental contamination;
-
Fewer number of mechanisms;
-
Industrial applications.
OPEN CARTRIDGE
Open ink machines have an ink reservoir that is exposed behind the plate. A spreader deposits ink on the plate and a blade scrapes off the ink, leaving only ink in the engraving cavity. Despite being an older system, it still has several advantages over the sealed cup.
BENEFITS
-
More alternatives in the process;
-
It is possible to exploit the maximum capacity of the pad printing process;
-
Minor clichés;
-
Better use of the useful area of the plate;
-
Supports printing in large areas (including multicolor);
-
Possibility of using different sizes of clichés in the same type of machine;
-
Possible to scrape only part of the cliché;
-
Professional applications;
-
Flexibility to switch from single to multi-color;
-
Permanent visual contact with all process variables.
