Printing network introduction and its function

Madontho yosindikiza kusewera ndi udindo wofunika kwambiri. Madontho akhoza kusamutsa gradations ndi milingo, ndi mitundu ya fano. mawunikidwe iliyonse kapena transmissions amapangidwa ndi tinthu pigment kapena particles siliva kupanga mosalekeza ukufalikira kamvekedwe. Izi kamvekedwe ukufalikira ndi wosanjikiza ayenera kujambulidwa kapena njira zina gawo fano mu madontho yaikuluikulu.

  Madontho ndi unit ofunika kwambiri a zithunzi pa bwalolo, ndipo iwo ali ndi udindo kubereka ndi malankhulidwe wa pachiyambi atsogoleri bungwe, ndi ndondomeko ya fano. Malinga ndi mfundo ya maukonde, zikhoza kugawidwa mu magulu awiri a maukonde matalikidwe-modulating ndi maukonde pafupipafupi-modulating. Zoyambazo Anthu ambiri amagwiritsa ntchito. Kugwiritsa ntchito njira zosiyanasiyana (zowonetsera galasi, zowonetsera kukhudzana, njira zamakono magetsi kupatukana) akhoza kukwaniritsa mtundu wa ogulitsira, sipangakhalenso chimagwiritsidwa ntchito chifukwa cha zotsatira zake yosavuta, kudya, ndi bwino kulingalira. Pa nthawi yomweyo, anthu komanso ankadziwa bwino deficiencies, monga kuwonongedwa mtheradi wa moire, ndi chitukuko cha luso yosindikiza, anthu anayamba kuika maganizo awo mtundu wina Intaneti - FM zopezera malo ogulitsira.

  Pafupipafupi kusinthasintha mawu chiphunzitso mosamala zaonetseredwa kwa nthawi yaitali. Kumayambiriro 1993, a Agfa Division ndi Linotype-Gahena Corporation mwalamulo anapezerapo ndi FM maukonde mosamala luso. Mu August 1993, China anayambitsa Beijing University anayambanso FM yake mosamala luso.

  FM mosamala luso pali chithunzi ndi scanned ndi athandizira, pambuyo processing, kudzera chipangizo linanena bungwe pamene mfundo yomweyo kukula ndi mosintha kufalitsidwa ku malo osiyana, chiwerengero cha mfundo ndi osalimba, ndiye pafupipafupi kuoneka mfundo maukonde, mu kuyitanitsa kusonyeza chithunzi kachulukidwe ndi utsogoleri wolowezana wa njira luso. Choncho, fineness wa fano akuimira salinso anafotokoza ndi chiwerengero cha mizere utoto uliwonse centimeter, koma ndi chimafotokozera kukula kwa madontho. Zing'onozing'ono ndi dontho kukula, ndi apamwamba molondola fano limene akhoza zinkaimira. The bwino.

  luso limapanga zithunzi pafupi ndi mavuto Zithunzi. Chifukwa cha magulu kukhudzana mu ndondomeko Zithunzi, pali kusiyana mu kuchuluka kwa particles photosensitive siliva mchere mu dera limodzi. Pambuyo chitukuko, pali ochepa siliva ta mchere pa osalimba otsika pa chithunzi, ndipo pali ambiri asiliva mchere particles pa kachulukidwe mkulu, ndi kusintha kachulukidwe anatsimikiza ndi nambala ya particles siliva mchere m'madera osiyana. Izi zikufanana ndi maukonde FM, ndi matalikidwe a malo AM ndi osiyana. Iwo anafotokoza kukula dontho (chiwerengero), chotero sangathe kukwaniritsa zotsatira za pafupi ndi kujambula.

  Pakali pano, makampani anayambitsa nyumba dontho osiyana ndi kupatsidwa maina osiyanasiyana monga Agfa a "Crystal Network", Linotype-Gahena "Daimondi Network", Dainippon Screen a "RANDOT", etc. Choncho, chiwerengero ndi malo madontho kusindikizidwa lililonse chithunzi m'dera wagawo ndi osiyana, koma onse a mosamala FM.

  The mauna kukula kwa kuyezetsa magazi ndi FM zimadalira chigamulocho linanena bungwe ndi magawo mosamala. Mwachitsanzo, ngati chigamulocho linanena bungwe ndi 2400 DPI, ndi mosamala chizindikiro ndi 2 × 2 laser madontho monga mfundo network chophimba awiri ndi 21 μm; magawo mosamala ali ndi madontho 3 × 3 laser ngati dontho, ndi dontho awiri ndi 32 μm.

  Mu ndondomeko lonse, chinthu chachikulu kwambiri ndi kutembenuka ndi kusintha kwa maukonde FM. Phata ndi kusankha yoyenera randomness ndi laser mtengo awiri. Kumene kwaiye FM mfundo maukonde yosalala ndi olimba, yunifolomu kukula, ndipo ndi pang'ono akutali kuwala mawanga, umene uli ofunika kulamulira khalidwe. The watsopano amakwaniritsa typesetting makina lamulo limeneli. The awiri laser mtengo zikhoza kusintha malinga ndi kukula dontho. Komanso kuti kugwirizana ndi ndondomeko lotsatira, chidwi ayeneranso analipira yosankha dontho phindu, lomwe n'zotheka kuti lizilamuliridwa mkati osiyanasiyana 5%. Kuwonjezera pa pamwamba, zithunzi za zithunzi ayenera kutsukidwa ndi chidwi kutentha, liwiro, ndi mfundo pH, ndipo tiyenera kutsukidwa ndi mkulu-liwiro masitampu otentha kuonetsetsa khalidwe la maganizo. Kumbali ya ntchito yosindikiza mabuku, chifukwa chakuti palibe malire kwa nsalu yotchinga ngodya pafupipafupi kusinthasintha mawu, yolondola zida overprinting m'malo otsika, ndi inks mtundu amene nthawi zambiri ntchito komanso zovomerezeka.
