DIN-test charts according to DIN 33870:2001-01 with german text: DG02

Proposal of DIN-test charts for a future version of DIN 33870:
1. with english text and the MTL code in the distiller startup directory: DE22
2. with german text and the MTL code in the distiller startup directory: DG22
3. with german text and the MTL code in the files: DG02A

1. Version and changes
20021001: New improved version 2.0 of this material for the test and the documentation with tables and figures of the results in step S3.

The steps S1 and S201, S202, ..., S209, S210 include additional test pages no. 1 to 7 for the test of the reproduction properties in comparison with the OEM modul.

2. Test goal and short description of the test procedure

It is asumed that the series no. 1 to 10 are reproduced by 250 pages each.
In the following step S201 only seven pages are reproduced as reference.

Step S1: Start output of series no. 1 with 250 pages.
The CIE lightness L* data of the 16 grey steps on the end page (Step S1, page 250) are measured and used for the linearized output of the steps S201, S202, ..., S209, S210 (Output of 7 pages and 9 series of 250 pages each) as well as for the result documentation in step S3.

Step S201: Linearized output of Step S201 (250 pages, special test pages 244 to 250 as reference) of the series no. 1 in Step S201.
The CIE lightness L* data of the 16 equidistant grey steps on the end page (Step S201, page 250) are measured and used for the result documentation in step S3. The pages 244 to 250 are used for reference also

Step S202, S203, ..., S209, S210: Output series no. 2 to 10 of 1/10 (250 pages) of the declared OEM yield with 5% area coverage black and the additional test pages no. 1 to 7.

Step S3: Output of 10 pages with two tables and figures for the specification of the reproduction properties (CIE lightness differences L* ) of the 16 grey steps in the L* device output range according to the method given in Annex G of DIN 33866-1:2000-08 and ISO/IEC 15775:1999-12.
The tables and figures are produced from the measurement of the 16 grey steps of the pages 250 of series no. 1 in step S1 and of page 250, 500, 750, ..., 2500 of the series no. 1 to 10 in step S201, S202, ..., S209, S210. All measurement data are included in only one file which produces an output of 10 pages to show the reproduction properties of the series no. 1 to 10.

Step S2xx: Linearized output of Step S201 (250 pages with pages 244 to 250 as reference) with 16 equidistant grey steps on page 250 and linearized output of the Steps S202, S203, ..., S209, S210 (250 pages each with 16 equidistant grey steps on page 250) Serves for the linearized output which means production and measurement of the equidistant 16 grey steps and of the 7 special test pages der Stufen S201 bis S210

The yield of a cartidge is described as a ratio of the numbers of pages produced by the refilled modul compared to the OEM modul. The printed pages of the series S101 and S201 to S209 add to 2500 pages. If additional output is necessary then the series S210 may be used several times.

Remark: It is recommended to print step by step the pages 1 to 250, 251 to 500, ..., 2000 to 2250, 2251 to 2500 of the steps S201, S202, ..., S209, S210 from the file A02GS02FP.PDF (produced from A02GS2FP.PS by the software Adobe Acrobat Distiller).
