Can you solve these mystery puzzles?
When troubleshooting a screen printing job exhibiting pinholing in the emulsion, and the ink viscosity is confirmed to be within the optimal range, what is the most likely root cause related to the emulsion process itself?
A screen printer is experiencing "choking" of fine details in their prints, where the ink appears to spread outwards beyond the intended stencil boundaries. The emulsion is properly exposed and dried, and the mesh count is appropriate for the design. What troubleshooting step should be prioritized to address this issue?
During a high-volume print run, a screen printer notices a gradual increase in "bridging" – where ink fills in small gaps between adjacent stencil elements, blurring fine details. The emulsion is consistently applied, and the ink is not drying on the screen. What is the most probable cause of this escalating bridging?
