The RIP's role in FM Screening involves executing complex algorithms for the distribution of fixed microscopic dots. Unlike AM Screening which uses a regular grid, the RIP must calculate the location of the dots semi-randomly yet precisely to reproduce tones. This computational process ensures that the dot density correctly simulates color values. The RIP output is then sent to the CTP device.

The CTP device requires a very high Resolution (at least 2400 DPI) to accurately image these minute dots, typically measuring 10 to 40 μm, onto the plate without error. Even a small imaging error can affect mid-tone stability. Therefore, the technical team must ensure the RIP is constantly updated with press calibration profiles. This level of precision makes FM a technique that, while offering high quality, demands greater expertise and accuracy from technical personnel.
