Technikailag a piramis alak\u00fa cell\u00e1k szerkezeti jellemz\u0151i korl\u00e1tozz\u00e1k a tinta \u00e1raml\u00e1s\u00e1t, \u00edgy b\u00e1r a tintat\u00e1rol\u00f3 kapacit\u00e1s megn\u0151tt, a t\u00e9nyleges tinta\u00e1tvitel nem javult hat\u00e9konyan. Ezzel szemben a piramis- vagy m\u00e9hsejt alak\u00fa cell\u00e1k jelent\u0151s el\u0151ny\u00f6kkel rendelkeznek. Nemcsak nagy tintat\u00e1rol\u00f3 kapacit\u00e1ssal rendelkeznek, hanem a tinta \u00e1tvitele is sim\u00e1bb.

Ez\u00e9rt a hengerprobl\u00e9m\u00e1k megold\u00e1s\u00e1ra megfontolhatja a kett\u0151s nyomtat\u00e1si m\u00f3dszer alkalmaz\u00e1s\u00e1t.<\/p>\n

(2) A nyom\u00f3gumihenger alkalmass\u00e1ga az aljzathoz<\/p>\n

Ha a nyomdahenger kem\u00e9ny, a hordoz\u00f3 pedig puha, a kett\u0151 k\u00f6z\u00f6tti kem\u00e9nys\u00e9gk\u00fcl\u00f6nbs\u00e9g miatt t\u00fal kev\u00e9s fest\u00e9k ker\u00fcl a cell\u00e1kba.

3. A nyomtat\u00e1si nyom\u00e1s pontos szab\u00e1lyoz\u00e1sa<\/p>\n

Ha a nyom\u00f3nyom\u00e1s t\u00fal alacsony, a cell\u00e1kban l\u00e9v\u0151 fest\u00e9k nem lesz el\u00e9gg\u00e9 \u00f6sszenyomva, ami elker\u00fclhetetlen\u00fcl rossz fest\u00e9k\u00e1tvitelhez vezet. A nyom\u00f3nyom\u00e1s kulcsszerepet j\u00e1tszik a tinta\u00e1tvitel folyamat\u00e1ban, ak\u00e1rcsak a sz\u00edv pump\u00e1lja a v\u00e9rt. Ha a nyom\u00e1s nem el\u00e9gs\u00e9ges, a tinta nem tud teljesen \u00e1tker\u00fclni a hordoz\u00f3ra. Ez\u00e9rt a nyomtat\u00e1si nyom\u00e1s megfelel\u0151 n\u00f6vel\u00e9se hat\u00e9kony m\u00f3dja a probl\u00e9ma megold\u00e1s\u00e1nak, ami el\u0151seg\u00edtheti a jobb fest\u00e9k\u00e1tvitelt a cell\u00e1kb\u00f3l, \u00e9s ez\u00e1ltal n\u00f6velheti a fest\u00e9kr\u00e9teg vastags\u00e1g\u00e1t.<\/p>\n

4. A hordoz\u00f3 fel\u00fcletkezel\u00e9se \u00e9s a nyomtat\u00e1si id\u0151<\/p>\n

Ha a f\u00f3lia fel\u00fclet\u00e9t kezelik, majd hossz\u00fa ideig t\u00e1rolj\u00e1k, a fel\u00fcleti tulajdons\u00e1gok megv\u00e1ltoznak, ami a tinta rossz nedvesed\u00e9s\u00e9t \u00e9s tapad\u00e1s\u00e1t eredm\u00e9nyezi. Ennek oka, hogy id\u0151vel a f\u00f3lia fel\u00fclete a leveg\u0151ben l\u00e9v\u0151 szennyez\u0151d\u00e9seket adszorbe\u00e1lhatja, vagy oxid\u00e1ci\u00f3s reakci\u00f3n mehet kereszt\u00fcl, ami cs\u00f6kkenti a tinta ir\u00e1nti affinit\u00e1s\u00e1t.

Ez\u00e9rt a nyomtat\u00e1st a hordoz\u00f3 fel\u00fclet\u00e9nek kezel\u00e9se ut\u00e1n azonnal el kell v\u00e9gezni, hogy a fest\u00e9k j\u00f3l tapadjon a film fel\u00fclet\u00e9hez, ami viszont el\u0151seg\u00edti a fest\u00e9kr\u00e9teg vastags\u00e1g\u00e1nak n\u00f6vel\u00e9s\u00e9t.<\/p>\n

A tintapigmentek magas koncentr\u00e1ci\u00f3ja t\u00falzott sz\u00e1rad\u00e1si sebess\u00e9ghez vezethet, ami negat\u00edv hat\u00e1ssal van a tinta \u00e1tvitel\u00e9re.

Ez\u00e9rt a pigmentkoncentr\u00e1ci\u00f3t \u00e9s a viszkozit\u00e1st \u00e9sszer\u0171en kell be\u00e1ll\u00edtani, hogy megtal\u00e1ljuk a kett\u0151 k\u00f6z\u00f6tti optim\u00e1lis egyens\u00falyt, hogy a fest\u00e9k a nyomtat\u00e1si folyamat sor\u00e1n sim\u00e1n \u00e1tvihet\u0151 legyen, mik\u00f6zben j\u00f3 sz\u00e1rad\u00e1si tulajdons\u00e1gokat tartunk fenn, ami el\u0151seg\u00edti a fest\u00e9kr\u00e9teg vastags\u00e1g\u00e1nak stabil javul\u00e1s\u00e1t.<\/p>\n

A f\u00f3li\u00e1k a nyomtat\u00e1s sor\u00e1n hajlamosak a statikus elektromoss\u00e1gra, ami zavarhatja a tinta\u00e1tvitel folyamat\u00e1t. A statikus elektromoss\u00e1g hat\u00e1s\u00e1ra a fest\u00e9kr\u00e9szecsk\u00e9k az \u00e1tviteli folyamat sor\u00e1n elmozdulhatnak, vagy a nyomdai berendez\u00e9shez tapadhatnak, ahelyett, hogy egyenletesen tapadn\u00e1nak a hordoz\u00f3ra.

Ez\u00e9rt el\u0151sz\u00f6r meg kell sz\u00fcntetni a statikus elektromoss\u00e1got a f\u00f3li\u00e1n, majd elektrosztatikus tintaelnyel\u0151 eszk\u00f6zt kell haszn\u00e1lni a tinta\u00e1tviteli sebess\u00e9g jav\u00edt\u00e1sa \u00e9s annak biztos\u00edt\u00e1sa \u00e9rdek\u00e9ben, hogy a tintar\u00e9teg vastags\u00e1ga megfeleljen a k\u00f6vetelm\u00e9nyeknek.<\/p>\n
