Why isn’t my pad printing doctoring the cliches?

There can be multiple reasons for this issue. Let's explore some of the most common ones:

Reason 1: Insufficient Ink Usage

If you have a low production run and attempt to use less ink in the ink cup to minimize waste, it can lead to problems. To ensure proper functionality, the ink cup must be filled to the minimum amount that allows it to efficiently doctor the cliché. Therefore, it is important to use an adequate amount of ink to achieve the desired results.

Reason 2: Scooping - Bald Spots on Prints

Scooping can occur due to two reasons. Firstly, when using magnetic ink cups, the magnetic pull can sometimes deflect the cliché, causing it to "scoop" ink from certain areas. Secondly, if there is a bold etch and insufficient support for the ink cup, it can result in the ink cup dipping into the etch and gradually scooping out ink over time. This can lead to uneven ink distribution and the formation of bald spots on the prints.

To address these issues, it is recommended to ensure that the ink cup is filled appropriately and that there is sufficient support for the cup to prevent scooping. Maintaining proper ink levels and ensuring stable contact between the cliché and ink cup can help resolve the problem of bald spots on print
