The print area of an open system is generally much larger than with a sealed system because there are no major limitations as to how wide a doctor blade or plate can be made. Long images on plastic housings (i.e. televisions, computer monitors, vacuum cleaner parts) are usually pad printed with an open well machine.

Doctor blades are much cheaper than Closed-cup. more designs can be accommodated in Pad Printing Plate thereby reducing Cost per print

Color adjustments are made quite easily with an open system, especially when the color needs to be modified on the fly. Color Registration in case of Multi-Color printing is also very fast. Closed systems present problems with color adjustment because they only have a small access hole for adding ink or thinner. Looking at the ink to adjust color is simply impossible

Closed-Cup Pad Printing Machine’s only moving part is the sealed ink-cup which does the doctoring operations. and can be managed easily. Highly trained operators are hard to come by in these times therefore it makes the first choice for new customers who have just started Pad Printing

As the INK used is poured in a sealed cup it doesn’t come into contact with Air therefore there is no Evaporation and no pungent Odor moreover it reduces your INK requirement. This makes a lot of difference if you are using EXPENSIVE inks

Closed-cup machine uses less moving parts compared to Open Inkwell machines therefore can be placed in cramped places.
