Dutch to English translations [PRO]
Tech/Engineering - Printing & Publishing | | Dutch term or phrase: kaallopen | I am currently working on a small translation (article about two production departments), and am struggling with the above term.
The context is as follows:
"De Pre-Press afdeling houdt zich met name bezig met het produceren van offset drukplaten. Deze platen gaan in de printer en zorgen er mede voor dat de gewenste afdruk gemaakt kan worden. Enkele problemen waarmee ze geconfronteerd worden zijn het scheuren en het kaallopen van de plaat. Dit laatste houdt in dat de afbeelding op de plaat zodanig versleten is dat deze niet meer gebruikt kan worden."
I have consulted my Kluwer dictionary and various online dictionaries / websites, all to no avail!
All suggestions welcome - KudoZ points will be awarded within 72 hours.
Many thanks,
Anne |

| | premature plate wear | Explanation:
Based on the references given below, I think that "premature plate wear" would be a good option. I think the word "premature" is a useful addition to differentiate it from normal wear.
kaallopen
Een probleem dat ontstaat op de offsetdrukplaat door een verkeerde persafstelling of door het gebruik van teveel aan antismetpoeder. Door schuring verdwijnen de druktechnische eigenschappen van de offsetplaat.
Oorzaken van kaallopen kunnen zijn:
- slechte kwaliteit van de offsetplaat
- inwerking van papierstof of anti-smetpoeder.
- drukken met een te hoge drukspanning.
- slecht afgestelde inkt- en vochtopdraagrollen.
- schuren tussen de verschillende cilinders (verschil in omtreksnelheid).
- te veel en te zuur vochtwater.

Plate wear depends on roller setting
Rapid and extensive wear of a lithographic plate may result from excessive ink roller pressure. Pressure causes friction removal of image detail and of the protective gum that coats a plate's surface. The plate's life expectancy suffers considerably and, in some cases, it may fail to survive a long press run.

Premature Plate Wear
Poor plate life results whenever a plate image wears out prior to the time specified by the plate manufacturer. The plate image area is actually a polymeric chemical coating on the surface of the plate. Although hardened by exposure to light and heat (also called "baking"), it is still subject to abrasion or mechanical wear from several sources.
Poorly ground or inadequately dispersed inks, as well as ink that contains abrasive pigments such as titanium dioxide and some extenders, are all potential sources of premature image wear. Metallic inks may be particularly bad offenders. In these cases, the plate image area simply gets "ground off" and disappears.
Hard and/or improperly set ink form rollers will wear the image area prematurely, because they exert more rubbing forces on the image than it is designed to take. Excessive pressure or "squeeze" between the plate and blanket can have the same effect.
Even the choice of the wrong fountain concentrate, particularly one that results in a mixed pH below 3.5, as well as an incorrect dosage can result in a poor quality ink/water emulsion. If this emulsion is very thick and tacky or gummy, this paste-like material will cause premature image wear.
When these wear problems occur, the printer must replace the plate in order to restore good print quality.

| Grading comment My client was happiest with this suggestion, as the addition of "premature" differentiates it from normal wear and tear. Apologies for the rather ambiguous source text!
