This magnifying lens helps shops check their exposure time. Options on this tool can range anywhere from a basic handheld version to a high-end, electronic microscope.
According to Magnifier.com, printer loupes are used for:
- Analyzing text, colors, type size, offsets, and registration
- Inspecting type size and quality
Matt Marcotte, T&J Printing Supply, suggests searching for a reliable unit over the priciest version. The primary function should allow a shop to check exposure and make sure they have clean, hard edges and proper coating.
