Abstract
Maqolada inkjet va lazer bosma texnologiyalarida rang barqarorligini shakllantiruvchi fizik kimyoviy va texnologik omillar Epson, Canon va Kyocera printerlari misolida qiyosiy tahlil qilindi. Tadqiqot laboratoriya tajribasi sifatida emas, balki standartlar, ishlab chiqaruvchi texnik hujjatlari va ilmiy adabiyotlarga tayangan analitik tadqiqot sifatida tashkil etildi. Rang barqarorligini baholash uchun CIELAB koordinatalari, CIEDE2000 rang farqi (ΔE00), optik zichlik, rang gamuti, gloss hamda vaqt bo‘yicha drift mezonlari asosiy indikatorlar sifatida belgilandi. Epson EcoTank L8050 ning olti rangli dye-ink tizimi, Canon PIXMA oilasidagi ChromaLife/FINE yechimlari va Kyocera TASKalfa rangli lazer tizimlarining toner-fiksatsiya mexanizmi taqqoslandi. Tahlil dye asosidagi inkjet bosmada rang to‘yinganligi va fotografik silliqlik yuqori bo‘lishi mumkinligini, biroq natijaning media, ultrabinafsha nurlanish, ozon va namlikka sezgirligini ko‘rsatdi. Pigment asosidagi inkjet tizimlari uzoq muddatli saqlanish va yorug‘likka chidamlilikda ustunlikka ega. Lazer bosmada esa tonerning issiqlik va bosim yordamida qog‘oz yuzasiga fiksatsiyasi operatsion barqarorlik, suv va ishqalanishga nisbatan chidamlilikni oshiradi.
