Print paper chart

High definition on a paper base. Large sizes can also be created. This is a reflective chart characterized by a matte finish on the pattern surface.

The print paper chart is a reflective test chart made using black and white photographic paper, which is a photosensitive material. Equa's print paper chart comes in two types: a high-definition monochrome type that pursues fine line representation, and a gray type that takes advantage of the intermediate color representation unique to print paper. The former is used for calibration purposes of various optical products, resolution charts, distortion charts, and more. Typically, a film master is created first, and the print paper chart is produced based on that. It is drawn using a high-precision parallel light source exposure machine in a clean room managed at 23 degrees Celsius and 50% humidity. The unique exposure process reproduces the highest level of sharp pattern edges. Patterns can be created with a minimum line width of 30 micrometers. The latter is used for creating products for color management of scanners and optical devices. A pattern featuring step tablets and solid patches is representative. Reflective density, number of steps, and arrangement can be customized. The product can measure reflective density and is also compatible with the creation of color products. *For more details, please download the catalog or contact us.*
