ColorFlow supports the following types of measurement charts (with generated response types):

  • Tint Ramp (Tonal only)
  • Tonal only (Tonal only)
  • P2P25 or P2P51  (Gray Balance and Tonal)
  • TC1617x (Tonal control with gray balance and color relationship management)
  • Full Color and Tonal

A measurement chart contains all color patches required to determine the color, gray balance, or tonal response of a printing device. It includes all necessary identification and branding information that can be printed on either a single chart form or multiple chart forms, depending on the chart type and your printing device. A chart form contains one or several measurement pages. A measurement page is the portion of a chart form that can be measured by a color measurement device. It contains a footer and color patches that are a few millimeters in width. The total number of patches in a chart form, depending on the intent of the characterization (tonal, gray balance or full-color response) and the number of process inks that are used. A full-color characterization chart for a CMYK inkset requires about 1600 patches spread over multiple measurement pages, whereas a tonal characterization chart for the same inkset requires only a small single-page tint ramp chart, potentially consisting of as few as five patches. The maximum size of a measurement page is limited by the measurement device and the uninterrupted printable area on the print device.

The following shows an example full-color characterization chart that consists of four measurement pages in a single chart form:

  1. Chart form
  2. Measurement page
  3. Patch

If you only want to generate print calibration curves, you can:

If you want to do a full-color characterization in order to generate a device profile or DeviceLink (only available in ColorFlow Pro Workflow edition), measure a Full Color and Tonal chart

Charts for G7 support

ColorFlow clients also have these three additional built-in charts for G7 support, each of which can be exported as a PDF file:

  • TC1617x (i1iO) cf
    This chart can be measured by i1iO and i1iO2 only, scanning for any measurement conditions supported by the connected i1iO.
  • TC1617x_H (i1iSis) cf
    This chart (as well as the TC1617xV cf chart) can be measured by i1iSis and i1iSis2 only, with any measurement conditions supported by the connected i1iSis.
  • TC1617x_V (i1iSis) cf

Activation of any of the above measurements produces a Full Color and Tonal response for process inks, and measurements of any chart can be exported. In a report generated by any of these measurements, CIELAB measurements reported for the device or verified output are same values that appear in exported measurements.
