Abstract
Evalueringen av trykkbarhetsegenskapene til papirer har inntil nå fremfor alt skje ved den subjektive, visuelle rubrisering av et trykkmønster ved opplært fagpersonale. Den nye fremgangsmåte skal med forbedret holdbarhet og lønnsomhet muliggjøre en evaluering av trykkvaliteten av trykkmønsteret på grunnlag av måleteknisk innsamlede informasjoner. Trykkbildet til et trykkmønster blir registeret ved hjelp av en vanlig skanner digitalisert, videre- behandlet og evaluert ved hjelp av et opplært nevralt nett. For å oppnå en overenstemmelse mellom evalueringen og den visuelle rubrisering blir det neurale nett før måleoperasjonen i en lærefase lært opp ved hjelp av trykkstandarder med kjent rubrisering. Bruk til måling og evaluering av trykkforstyrrelser som melering, blistere eller "missing dots", foretrukket ved bestrøket papir.Up to now, the evaluation of the printability properties of papers has primarily been through the subjective, visual rubrification of a print pattern by trained professionals. The new method will, with improved durability and profitability, enable an evaluation of the print quality of the printing pattern on the basis of information collected from measurement technology. The print image of a print pattern is registered by means of a standard scanner digitized, processed and evaluated using a trained neural network. In order to achieve an agreement between the evaluation and the visual rubrication, the neural network prior to the measurement operation in a learning phase is trained using pressure standards with known rubrication. Use for measuring and evaluating printing disorders such as blistering, blisters or "missing dots", preferably with coated paper.
