MAQOLA ANNOTATSIYASI

Domimiy, stoxastik va gibrid rastrlash usullari bilan qayta ishlangan tasvirlarda rastrli tuzilma xossalarining ranglarni hosil qilishga ta’sirini o‘rganish uchun kolorimetrik parametrlar va rang o‘zgarish qiymatlari aniqlangan. Rangni hosil qilish sifatini obektiv baholash uchun Toshkent shahridagi (O‘zbekiston) MChJ «ANIS POLIGRAF» ishlab chiqarishi sharoitida Speedmaster CX-104 ofset bosma uskunasida nusxalar olingan. Bo‘yoqning bir tekis uzatilishini nazorat qilish bilan bir qatorda chop etish va unga ko‘ndalang yo‘nalishlarda rang tavsifnomalarining o‘zgarishi baholandi. Buning uchun nusxalarda kolorimetrik o‘lchashlar amalga oshirildi, chunki ular rang farqlanishlarini aniqroq tavsiflab beradi. Aniqlandiki, doimiy, stoxastik va gibrid rastrlash usullaridan foydalanilganda nusxalarda ranglarning aniq uzatilishi ta’minlandi, chunki nuqtalarning kattalashuvi qiymati ΔE 1 gacha, rastr nuqtalari o‘lchamlari va shaklining buzilishi minimal, tasvirlar asl nusxaga to‘liq mos keladi, demak foydalanilgan bosma uskunasi berilgan ranglarni aniq hosil qilgan.
