Q1Domain Verified
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?
Over-exposure of the emulsion, leading to a hardened stencil that repels ink.
Insufficient drying of the emulsion before stencil creation, causing it to lift during exposure.
Inadequate emulsion coating thickness, resulting in a stencil too thin to fully block ink in microscopic areas.
Contamination of the emulsion with uncured sensitizer, creating areas of weakness.
Q2Domain Verified
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?
Adjusting the squeegee angle to a more acute (lower) angle to reduce ink shear.
Increasing the squeegee durometer to provide more precise ink laydown.
Increasing the emulsion stencil thickness to create a more defined barrier.
Reducing the squeegee pressure to minimize ink spread.
Q3Domain Verified
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?
The squeegee is losing its sharp edge, leading to less efficient ink shearing.
The stencil is degrading due to excessive solvent content in the ink, causing it to soften.
The underbase ink layer is too thin, allowing the top color to bleed into it.
The mesh tension is decreasing over the print run, allowing the squeegee to push ink through larger openings.
