Results of the study of:Sappi Spectro C1S 10ptSappi NA04/04/2019

As conducted on the:Kodak NexPress ZX3900 Digital Color PressIn accordance with version 5.0 of the Kodak NexPress Substrate Qualification Procedure

RIT offers this substrate qualification consistent with guidelines agreed to with Kodak.

This report documents the results of an evaluation performed on the media identified, in RIT’s controlled testing environment. This report is supplied to the media manufacturer by e-mail at the completion of a successful evaluation, and a shortform version of the qualification details is posted on RIT’s listing of NexPress qualified substrates. Any change to the substrate properties should motivate resubmitting the substrate for re-qualification. Results of this evaluation and the qualified status of the submitted substrate are valid for a period of 4 years, after which the substrate and its script will be removed from the online listing of qualified grades pending a new qualification.

* Substrate top surface is considered to be the surface facing the seam of the ream for ream wrapped sheets, or the upward facingsurface of boxed or pallet wrapped sheets.

** Resistivity and Moisture Content are recorded after the substrate has acclimated to the controlled condition of the testing lab (70 °F/50%RH) and are conducted on unwrapped or out of ream stock prior to the substrate evaluation.

Substrate Qualification Performance Report 3

Substrate Qualification Process Machine Information

Engine Number: # 0508-SASoftware Version: 16.00 RC09-K

Qualification Runs: EvaluationsRIT conducts a number of evaluations, to determine the optimum engine dependent settings, for the particular substrate. Selection criteria for the different settings are based on: DryInk adhesion, gloss differential, color density, overall image quality, and no artifacts such as excessive curl, wrinkling, or blistering.

The Process of Substrate Qualification contains the following steps1. Runnability Screening Test2. Press and Substrate Linearization3. Fusing Evaluation 14. ICC Profile Selection5. Fusing Evaluation 2 (Assignment of Substrate Fusing Grade Rating) 6. Runnability Full Evaluation (Assignment of Substrate Runnability Grade Rating)

Explanation of Star Ratings

Beginning with qualification procedure version 5.0 Kodak has introduced a star rating system as part of the qualification procedure to allow for differentiation among grades within the areas of fusing and runnability. Grades evaluated will receive a grade of 0 to 3 stars depending on their performance in the identified areas with 3 stars representing substrates with the best performance. A grade of 1 star is required for the substrate to pass the qualification procedure and have it’s script file added to the online list of qualified grades.

The Table below describes the criteria for the achievement of the 3 levels of star ratings:

Attribute Evaluation Best Good Fair Failure

Fusing

Adhesion of toner to substrate (Standard)

Fusing related failures (wrinkles, curl, fuser lakes/rivers, corner folds, BC wraps)

Excellent Adhesion

and

No Fusing related jams or failures

Good Adhesion

or

Minimal impact of temperature on substrate

Acceptable Adhesion

or

Some impact of temperature on substrate

Poor Adhesion

or

Significant impact of temperature on substrate

RunnabilityFeed and Transport related failures (jams, double feeds, stacking quality)

No feed or transport failure

1 feed or transport failure

1 feed or transport failure

>1 feed or transport failure

Image Quality

Image & Print Quality (IQ/PQ) Issues(roller track marks, contamination buildup)

No IQ/PQ issues 1 Minor IQ/PQ issue 1 Minor IQ/PQ issue >1 Minor IQ/PQ issue

Structured paper (uniform ink density)

No loss of density throughout structure

Faint loss of density throughout structure

Noticeable loss of density throughout structure

Notes This product functions as expected under the evaluation conditions and is qualified for the Kodak NexPress 2100 Classic through the Kodak NexPress S3000 platforms with the application of HD toner and the appropriate Kodak NexStation Digital Front End software.

Interpolated Test: Performance Script for this test was interpolated from the 8pt, 14pt, 20pt, and 24pt weight qualifications.

Concerns There are no concerns with this substrate as a result of the qualification process.

Release Date The expected release date for the Substrate Script file is Q2 2019.

This report is generated after Kodak provides its approval upon the results of the qualification testing at which point the script files are generated and added to online listing of qualified grades, the listing may be reached at the following address.
