Tupela Kain Kala Difrens Phenomeon Yu Mas Save Long Pekejing Printing

Problem blong kala difrens blong ol samting we oli printim long paket i bin mekem ol wokman blong printim buk oli harem nogud. Hevi bilong kala i narapela narapela inap long kontrolim gut. Em i mak bilong prodak kwaliti, nem na skil level bilong operesen masta bilong kampani. Olsem na ol hevi kampani i mas putim gut yau long en.

Kala we oli printim i klosap blong divaed long tu samting we i hapen, wan i minim: sem batch blong kala blong prodak, be wetem kala blong sample kala. Tupela i makim: wankain lain kala i gat kala, na sampela i stret wantaim sempel, tasol sampela i no stret wantaim sempel.

Nau long ol dispela samting mipela i laik toktok na skelim wantaim yu.

Namba wan, namba wan samting (em wankain lain prodak i gat wankain kala, tasol wantaim kala bilong sempel kala)

1, ol samting bilong man:

Na skil level bilong kepten i no gat wanpela samting bilong mekim, tasol wantaim tingting bilong kepten long wok, long wanem, wankain lain bilong prodak inap stap wankain, na dispela i soim olsem skil level bilong kepten i no liklik, tasol bilong wanem i no stret wantaim sempel i gat strongpela bel long prinim daun? Pastaim sain em? Dispela em i wok bilong kepten olgeta. (Na tu em i no rausim mak bilong asua, sapos em i olsem, dispela i pas gen long tingting bilong man i sainim).

2, pepa kala:

Pepa blong ol defren waet i gat ol defren ifek long kala lukluk blong printing ink leja. From we waet i sem mak long ol defren blak, red, blu o yelo long ink, so long printing nomata hamas ink, kala i no jenis, be ink we i rili gat wan spesel transperensi, ifek blong kala wetem pepa waetnes Ol samting i kamaot, we i mekem se i gat defren kala. Long opening, yu mas yusim wankain pepa. From hevi, saes, saes, nomata we i sem mak, be i sem mak, be fasin blong mekem ol defren deit blong batch, waet blong pepa ia bae i gat sam samting we i defren, we i risal long kala blong kala blong prodak we oli printim. Olsem na yu mas yusim wankain waitpela pepa olsem wankain pepa ol i prinim.

3, pepa glos na gutpela:

Gloss blong print i dipen long gloss mo smut blong pepa. Offset kala printing em i lait i bin kamap long pepa pes, lait i bin kamap long ai bilong man, long rot bilong lait-}sensitiv sel long kisim potosintesis na lukim kala. Sapos gloss na smut bilong pepa i antap, kala mipela i lukim em i as bilong kala i kamap long rot bilong ink leit, na bikpela kala lait saturesen i antap. Sapos pepa antap i no gutpela, gloss i daunbilo, em bai gat wanpela difus refleksen, em bai daunim saturesen bilong bikpela kala lait, olsem na ai bilong yumi manmeri i pilim kala bilong print i pilim lait moa. Ol i save skelim wankain ink densiti wantaim densitomita. Smutnes Glossy pepa, bikpela densiti. Smutnes i no bikpela tumas na i gat liklik strong.

4, ol i prinim pepa bilong pes:

Ol i prinim long rot bilong piksa, polisim, kalenda, antap long oil, printing na ol narapela tritmen bilong pes, bai i gat kain kain mak bilong ol senis bilong kala bilong kala. Sampela bilong ol dispela senis em senis bilong bodi, sampela senis bilong kemikal. Ol senis long bodi i kamap ples klia tru long prodak pes i skruim spekula refleksen, we i gat sampela impak long kala densiti. Olsem, dispela kompleks piksa, UV varnis, kalenda, na ol narapela samting, kala densiti bai go antap. Sab{5}}sab-film, matte kala printing long daunim bilong kala densiti. Ol senis bilong kemikal i kam long glu, varnis, UV oil na ol narapela samting. Ol dispela samting i gat planti kain kain samting bilong stretim, na olgeta dispela samting i mekim na kala bilong ing i senis. Olsem na, olsem paketing ofset printing, proses bilong prinim sapos i gat wanpela post-pres, ol senis long bodi na kemikel bihain long proses bilong prinim i mas kisim long tingting bilong painimaut densiti bilong printing ink na Lab veliu.

5, drai densiti veliu:

Prodak bilong printim ofset bihain tasol long printing, ink i stap yet long wanpela wet stet, orait mak bilong densiti veliu ol i bin metaim na mak ol i bin metaim bihain long draim densiti ol i bin prinim i narapela kain. Wet hai densiti, drai densiti veliu i daunbilo, dispela em i samting bilong drai-bek densiti veliu. Dispela em bikos ink ol i prinim tasol i gat wanpela mak bilong levelim. Pefomens blong fes blong mira- beis, i luk kalaful, i saen gud. Taem ink leja i drae, surface i gat difus refleksen, najoral laet i smol bitim taem oli printim. Long ol printing we oli stap printim oltaem blong mekem sua se ol batch prodak olsem we i posibol blong daonem kala, mifala i yusum sem wet densiti tes metod blong kontrolem. Em olsem, namba wan taim prodak i wet, kastoma i sainim na kwiktaim em i wanbel wantaim mak bilong wet densiti na veliu bilong L * a * b *. Bihain long ol i prinim prodak (wet stet), bihainim namba wan densiti veliu ol i bin metaim na L * a * b * veliu bilong kontrolim kala. I tru, sapos yu yusum wan densitomita wetem wan devaes blong polarisa, hem i save karemaot fes blong ink leja from spekula refleksen blong laet. Em i skelim wet densiti na drai densiti i klostu liklik, tasol tu inap helpim long daunim kontrol bilong kala.

6, presa bilong prinim:

Printing presa em i wanpela bilong ol kondisen bilong ink trensfe, bikos printing plet pes, blanket, na ol narapela samting i no inap stap stret tru, pes bilong pepa i no inap abrusim i gat ol liklik konveks o tiknes i no wankain. If the printing pressure is less than or uneven, the ink layer is prone to the phenomenon of uneven brightness, so the process required to achieve "three flat", which requires the printing plate surface, blanket and substrate and lining the surface to achieve a relatively flat Conditions, in order to thinner layer of ink through a balanced printing pressure to print on the print to get a more uniform ink color.

Taem presa blong printim i no inaf o i no stret, bodi blong laen blong laen mo ples blong printim plet long ples ia i no gat gudfala kontak, yu nid blong inkrisim amaon blong ink blong mitim ol layout ink visual ifek. Tasol dispela bai i no inap mekim ingk konsumsen tasol i go antap, tasol em bai isi tu long kamapim kala bilong prinim na prinim doti samting, olsem na "Sanping" (roller ink, wara rola, rola flat) yusim yunifom na oltaim printing Presa, long rot bilong stopim bikos long presa i no stret i kamap long kala.

7, bilong lukim lait bilong lait:

Ol samting bilong prinim i no gutpela long lukluk long kala i mas i gat lait sos, i no gat lait i no inap lukim kala, tasol sapos lait sos i no wankain, orait kala difrens bai gutpela tru. Long jenerol, yumi nidim kala obsevesen anda long ol najoral laet kondisen (hemia ol standet laet sos). Sapos yu yusim ol lait balb olsem lait sos kala, orait kala bai luk yelo, em i hat long luksave stret long kala, laspela prodak bai gat wanpela serios kala kast. Antap long dispela, strong bilong lait na lait angle bai i afektim tu kala aidentifikesen. Long wankain lait sos, sempel i lait long refleksen bilong lait intensiti, moa yet long sempel na lait sos long painimaut distens. Klostu strong, i no strong tumas. Olsem na mipela i save lukluk gut long tupela poin long taim bilong wok long san o nait: wanpela em long yusim wanpela standet lait sos (wevlength 400-700 o olsem), na narapela em long putim gut yau long lait sos strong na iradiesen angul i wankain. Long ol prodak we i gat bikpela kala, ol i mas putim ol 'printing ink' sempel antap long standet bilong skelim, olsem na bikos long lukluk long ol liklik samting i narapela long kala bilong aidentifikesen i stret tru. Olsem na, proses bilong praktis i tokim yumi olsem ol pasin bilong ol lait sos na lukluk long ol samting i narapela narapela bai i afektim stret kala bilong stretpela aidentifikesen.

Namba tu, namba tu samting (wankain kala i gat kala, sampela i gat wankain sempel, tasol sampela i no wankain wantaim sempel)

1, ol samting bilong man:

Se ol fes hue prospektiv, long ink i no balens yet long kes, i stat blong openem olgeta wei, proses blong printing blong non-stop adjustmen blong wota, ink, saed tune long saed, i fasem blong risal long sem batch blong kala print kala, Hemia i skil level blong kapten, eksperiens, fasin blong kapten i gat wan bigfala rilesensip, tufala i blong sem fasin blong mekem sem fasin blong mekem sem fasin blong mekem sem batj blong prodak blong prodak.

2, fonten solusen:

Offset printing em i yusim as tingting bilong oil- wara i no laikim. Dispela wara i makim rot bilong stretim fonten. Saes blong hem i afektem stret kala blong ink leja. Bikpela kala lait kala, wara, liklik ink leit bai kalaim dip. Taim wara i bikpela moa, emulsen bilong ing i bikpela moa. Emulsified ink matte, kala i lait. Ol samting ol i bin prinim long print ol i bin prinim, em i no kala nogut tasol, tasol ol i save kamapim tu doti, lusim, mak bilong mak i no strong, na olsem na ol hevi bilong kwaliti. Olsem na long wok bilong prinim, dispela wok i mas bosim gut sais bilong dispela marasin bilong prinim ol samting long plet bilong prinim buk, na wok gut long balens bilong ing na ink. Ol i mas i gat liklik wara, moa gutpela.

3, spit bilong prinim:

Spid blong printing bae i afektem kala blong print samting. Dispela i kamap, long wanem, spit bilong ka bai helpim ink balens. Ekspresem plet blong wota mo slo vesen blong wota long plet i difren. Ekspres plet evaporesen bilong wara em i liklik, slo plet bikpela wara steam evaporesen. From we i gat ol jenis long saes blong wota, i mekem se ing i no stap stret, be i no save blokem se kala blong ing i jenis. Olsem na planti taim long printing i mas putim gut yau long wanpela spit i save kamap oltaim, em i no inap tru long draiv hariap. Inap liklik taim isi isi, olsem na ol print ol i prinim bai kamapim kala. Long semtaem tu i mas stanap long situesen blong masin, stretem i go long wan spid we i stebol moa. Olsem, sampela masin bilong prinim ol ofset ol i kisim long narapela kantri i soim olsem mak bilong 16,000 pepa / aua i spit tru na mak bilong spit bilong ol masin bilong haus em 8,000 pepa / aua. Ol dispela spit i no spit i stap gut. Long jenerol, tugeta masin we oli impotem mo domestik masin, stebol spid i 70% blong maksimal spid i ideal we i moa gud, hemia: impot masin long 11,000 / aoa, domestik masin long 5600 / aoa, spid ia i save isi blong kontrolem Ink balens, daonem kala.

4, rola nogut:

Proses blong printim we i no gud, ol samting we oli printim i save kasem yunifom ink kala, rola kwaliti i gat wan impoten rol tumas. Ol Jeneral Cots i gat ingk rola, ink rola na ink rola tri, ol i gat bikpela strong long ol ink kala sedo. Fleksibiliti, stik, raunpela, hat na pes pinis bilong ink rola i save makim bikpela hap bilong ingk ol i prinim. Sapos i gat ink rola nogut elastisiti, i no gat viskositi, rol eksentrik. Gutpela koloidal na koloidal i wok long kamap lapun, na ol narapela samting, wok bilong prinim i luk olsem em inap mekim ink i no wankain o i no stap gut, olsem na ol ink ol i redim ol ink i no wankain. Olsem na taim yu prinim bilong lukim olsem ol bet i gat gutpela kwaliti, bilong lukim olsem olgeta wan wan printing saikel i pas long plet bilong ing, em i wankain. Olsem na long wok ol i save mekim, ol i mas klinim raba rola na bai ol i ken rausim das bilong pepa na ol pipia i stap yet long raba rola na ing i ken i go long yunifom. Long semtaem, presa blong kontak bitwin ol rola blong ink mo ing rola mo plet blong printing tu oli mas stretem. Sapos nogat, ing i no stret inap kamap, na dispela inap mekim na kala bilong en i narapela kain tru.

5, mentenens bilong ol ikwipmen:

Wokim gutpela wok bilong masin em i wanpela samting yu inap bilip long en bilong helpim ing bilong prinim. Sapos masin i no stap gut, olsem, presa i no wankain, taim kaikai i no stap gut, planti taim wok bilong prinim ol samting i luk olsem em i emti, planti taim. I mas kamapim kala bilong kala bilong prinim. So planti taim yumi mas mekim gutpela wok bilong lukautim ol ikwipmen, lukluk long ol ki hap bilong masin lubrikesen, long stopim wear na tearim ol ikwipmen long wanpela stebol stet. Olsem wanpela ofset pres long mekim gutpela wok, "Miyoshi" (gutpela menesmen, gutpela yusim, stretim), "foapela laik" (bai yu yusim, bai sekim, bai stretim hevi).

I gat planti as bilong kamapim kala bilong prinim, ol rot bilong kontrolim tu moa long dispela, we i nidim yumi long lukluk oltaim long wok bilong prinim, bungim, kamapim gutpela pasin bilong kisim ol not i gutpela long kamapim gut inap bilong ol yet long lukim moa spesel taim Buk long tingting bilong printing, i gat ol tingting bilong ol kastoma i wok long kisim bikpela wok, long wanem, ol i gat bikpela tingting long mekim ol samting, long wanem, ol i gat bikpela hevi long ol kastoma, ol i ken kisim planti samting bilong rausim ol, long wanem, ol i gat bikpela hevi long ol samting ol kastoma i bin prinim. wan gudfala tingting Fes, bae yu stap long rod blong gat sakses moa mo i smut moa.
