How To Use Screen Printing Exposure Calculator
An exposure calculator help to dial in your exposure time. It uses a film positive with levels of a gradient, and the magic number is 7. An underexposed screen will have a low gradient level, so a 4, 5 or 6. This level will not allow enough ink to throw your screen while printing. Resulting in prints that do not have the detail intended. If your screen is over exposed your gradient level will be a 9 or above. This level means you have lost too much emulsion from your screen, so your screen will allow too much ink throw while printing. At an exposure gradient level of 7 your screen will wash out easier, retain detail, last through even the longest print runs, while still being easy to reclaim. Screen printing exposure calculators are a must for nailing the right exposure time. This can help by making your procedure of screen printing exposure move along much quicker and with less stress when there are other steps to get done as well.
