Test Chart for Printer Profile Measurement:

Default/Recommended Testing patches for single A4 and A3 paper size measurement:

Measurement Default: A4 size(1 page) with 924 patches(RGB), A3 size(1 page) with 2,226 patches(RGB)

Customer can also request to increase the number of patches for the measurement by increasing the total numbers of the A4 and A3 papers:

Various A4 and A3 page numbers give various number of patches for the measurement.

Maximum patches and page numbers: A4 size(total 18 pages) with 11,700 patches(RGB), A3 size(total 7 pages) with 11,466 patches(RGB)

Hence, Customer can specify page numbers of A4 paper size at the range from 2 to 18 pages and A3 paper size at the range from 2 to 7 pages

In practice, more patches provide more accuracy on the Printer Gamut information. It  improves the Printout details specially at the Dark Tone Color Gradation.   

If Customer is usig Raster Image Processing(RIP) software, the total number of patches for CMYK measurement are decided by the RIP "ICC Profile Measurement File". For instance: ColorBrust RIP-A3 size(1 page) with 1,511 patches(CMYK), EFI 4.0 RIP-A3 size(1 page) with 1,617 patches(CMYK).
