Qhov cim tshwm sim uas tsis pom rau digital print finishing

Cov lus qhia digital inkjet presses tau txhawj xyuam rau qhov kev txhawj xyuam ntawm kev txhawj xyuam ntau thiab kev txhawj xyuam raws li kev xav. Kev txhawj xyuam ntau dua, kev paub txog cov lus qhia uas muaj kev sib txawv, thiab kev txhawj xyuam zoo li kev txhawj xyuam hauv lub tsev txhawj xyuam tau ua rau lawv yog qhov tseem ceeb rau cov tsev txhawj xyuam hauv tsev. Tiamsis qhov kub tshab ib qho yuav tshwm sim rau qhov kev txhawj xyuam thaum suav: lamination. Cov thermal films sib thaj, uas tau tsim rau kev txhawj xyuam hauv lub tsev txhawj xyuam lossis kev txhawj xyuam digital uas muaj toner, yuav tsis tuaj yeem khiav tau zoo thaum txhawj xyuam rau cov khoom uas tau txhawj xyuam los ntawm inkjet. Qhov teeb meem—kev txhawj xyuam tsis zoo, kev muaj qhov tswb, lossis kev txhawj xyuam tsis tuaj yeem—yog tuaj yeem ua rau qhov kev txhawj xyuam zoo tshaj plaws tau ua pov tseg.

Kev tshawb xyuas lub siab ntawm 2024 qhia tias lub siab ntawm cov ntaub sib twj txijs rau kev sib twj txijs yuav tau nyob rau hauv $3.04 billion, thiab cov ntaub sib twj txijs rau kev sib twj txijs digital yog cov uas nyob hauv kev ceev dua li cov lwm yam. Qhov kev ceev no qhia tias muaj kev hloov pauv los ntawm kev sib twj txijs: cov neeg siv cov lus piav qhia tsis tuaj yeem siv cov ntaub sib twj txijs uas muaj kev sib twj txijs zoo ib yam rau txhua yam, thiab mus rau cov ntaub uas tau muab tsim los rau kev sib twj txijs ntawm cov lus piav qhia inkjet. Qhov nug yog tsis yog “yog puas yuav siv cov ntaub sib twj txijs uas sib npog rau cov lus piav qhia inkjet,” tab sis yog “yuav siv lawv li cas tsis txhob cuam tshuam rau kev ua haujlwm uas muaj lawm.”

Yog dab tsi ua rau cov lus piav qhia inkjet nyob hauv cov ntaub sib twj txijs nyob ib yam?

Kev paub txog qhov teeb meem txheej txheem yuav tsum pib ntawm cov lus piav qhia. Cov lus piav qhia inkjet uas muaj dej yog cov uas muaj dej, muaj cov lus piav qhia uas muaj dej nyob hauv cov dej uas yuav tsum rov qhia los ntawm dej los yog rov qhia los ntawm cov ntaub. Tsis zoo li cov toner, uas nyob hauv qab ntawm cov ntaub thiab sib twj txijs nrog cov dej, cov lus piav qhia uas muaj dej yuav rov qhia los ntawm cov ntaub. Qhov ntaub uas muaj dej no yuav ua rau muaj qhov xwm txheej uas muaj dej nyob hauv qab ntawm cov lus piav qhia thiab cov adhesive tom ntej.

Thaum cov ntaub ntawv thermal tshwj xeeb—txawm yog siv cov adhesive hot-melt tshwj xeeb—siv rau hauv qhov cim txias uas nyob hauv 100°C, cov dej tsis tau suav tawm hauv cov ntaub ntawv ink yuav tsaus mus rau hauv qhov cim txias. Qhov dej tsaus yuav ua rau cov adhesive tsis tuaj yeem tswj, ua rau cov neeg siv phais kom muaj “silvering” lossis cov ntaub ntawv tsis tuaj yeem tswj tau. Qhov teeb meem no yuav ntau dua thaum siv cov ntaub ntawv ink ntau lossis siv cov ntaub ntawv sib txawv, uas qhov ntaub ntawv ink yuav ntau dua.

Qhov kev daws teeb meem yog nyob rau hauv qhov kev sib npaug ntawm cov adhesive. Cov ntaub ntawv uas siv rau cov phais inkjet siv cov EVA uas muaj kev npaug lossis cov acrylic uas muaj kev npaug tshwj xeeb uas yuav tswj tau hauv qhov cim txias ntau dua—txawm yog 85°C rau 105°C, tsis yog 110°C rau 130°C uas yog qhov tshwj xeeb. Qhov cim txias ntau dua no yuav ua rau cov teeb meem uas muaj kev sib npaug nrog dej tsis tau suav tawm nyob ib puag ncig, thiab yuav tswj tau cov ntaub ntawv uas muaj kev tswj ntau dua lossis zoo ib yam rau cov ntaub ntawv tshwj xeeb.

Tshawb xyuam rau lub sijhawj ntawm cov phais tshuab rau cov khoom siv nyob rau hauv Chicago thiab uas siv ob qhov HP PageWide presses nrog rau cov khoom siv offset. Lub tsev phais tshuab no tau siv lub thermal lamination film zoo ib yam rau txhua qhov tshuab—offset, digital tshuab uas siv toner, thiab inkjet. Cov cim tshuab uas tsis raug tau siv rau inkjet tau ua ntev 8% thiab 12%, tshwj xeeb yog rau qhov tshuab tsis raug ntawm qhov rooj thiab qhov tshuab tsis raug rau qhov ntau tshuab.

Lub thawj coj kev lag luam tau ua qhov kev sim tswv yim rau lub film tshuab uas lawv siv los ntawm lub film tshuab uas muaj qhov ntsuas nqes ntau dua thiab muaj lub adhesive uas tau muab txiav txim. Rau peb lub hlis uas muaj ntau npaum 15,000 sheets ntawm cov khoom siv sib txawv—coated cover stocks, uncoated text papers, thiab synthetic media—the inkjet-compatible film tau ua ntev 1.2%. Lub tsev phais tshuab tau xam tau qhov nqi txiav tau ntawm cov khoom siv uas tsis raug thiab kev ua dua rau cov neeg ua haujlwm, uas muaj ntau npaum USD 18,000 rau lub lis piam, tsis nco rau qhov nqi tsis muaj tswv yim ntawm kev tsis nyab so ntawm cov neeg siv khoom.

Daim duab tseem ceeb: kev cog lus tsis xav tau cov khoom siv tshiab lossis kev txawj ua dua. Nws yog ib qho uas tsuas xav tau kev sib tham rau lub cim ntawm cov ntawv pov tseg thiab cov khoom siv pov tseg.

Cov KPI rau cov ntawv pov tseg rau lub cim ntawv pov tseg

Tsis txhawm cov ntawv pov tseg uas muaj lub npe "sib sod rau cov cim ntawv pov tseg" yuav ua haujlwm zoo tib yam. Cov neeg xa cov ntawv pov tseg thiab cov neeg saib xyuam kev ua haujlwm yuav tsum txheeb xyuam cov neeg sib tham rau lub tshuab tswv yim tib yam. Lub tav suav no qhia tias cov kev ua haujlwm tseem ceeb uas tau pom los ntawm cov kev txheeb xyuam ntau lub tsev.

Cov lej no yog los ntawm kev test nyob hauv lub tsev uas muaj ISO 9001 thiab muaj cov ntsiab uas muaj kev sib xyaw. Qhov tshwm sim yog qhov tseem ceeb: cov ntsiab tswv yim yuav ua kom zoo rau qhov thib cab, tab sis yuav tsis ua kom zoo rau qhov sib xyaw ntawm qhov ua haujlwm thaum ua kom zoo.

Kev ua kom zoo tsis muaj kev cuam tshuam rau kev ua haujlwm

Kev muab cov ntsiab uas muaj kev sib sod rau kev cog lus thiab kev cog lus tsis xav tau kev muab ua kom zoo rau qhov ua haujlwm thaum ua kom zoo. Kev ua kom zoo yuav muaj peb qhov kev ua.

1. Cov ntsiab lus thiab cov ntawv pov tseg. Qhia cov ntawv pov tseg thiab cov ntawv pov tseg uas tau siv rau hauv cov ntawv pov tseg digital. Cov ntawv pov tseg sib txawv—cov ntawv pov tseg gloss coated, cov ntawv pov tseg uncoated, thiab cov ntawv pov tseg synthetic—sib txawv raws li cov adhesive chemistry. Cov film uas ua hauj lwm zoo rau cov ntawv pov tseg matte coated yuav tsis ua hauj lwm zoo rau cov ntawv pov tseg uncoated uas muaj qhov txias ntawm cov felt. .

Yog cov cua sov ntau tshaj plaws yuav tso cov adhesive tsis ua hauj lwm ntau tshaj plaws; yog cov cua sov ntau heev yuav pib ua cov cua sov ntau heev uas muaj kev pheej yig rau cov cua sov ntau heev uas cov film tshiab tau txhim kho kom tsis muaj kev pheej yig.

3. Qhia cov ntawv pov tseg ua kom sov. Yog qhov tshwj xeeb tshaj plaws uas tsis tau xav txog. Cov ntawv pov tseg aqueous yuav tsum ua kom sov ntau tshaj plaws ua ntej lub sijhawm lamination—tsis yog sov rau ntawm qhov ntawv pov tseg, tab sis sov ntau tshaj plaws rau ntawm qhov ntawv pov tseg. Lub tsev ntawv pov tseg ib qho tau pom tias yog muab ntxiv lub sijhawm 24-hour thaum ntawm qhov ntawv pov tseg thiab qhov lamination yuav pab txo qhov kev pheej yig rau qhov ntawv pov tseg ntau dua 60%.

Yam tsawg ntawm cov ntaub ntawv uas tuaj yeem siv rau hais tswv yim thiab yam tsawg ntawm cov ntaub ntawv uas tsis tuaj yeem siv rau hais tswv yim

Cov ntaub ntawv uas tuaj yeem siv rau hais tswv yim tsis yog qhov tseem ceeb rau txhua qhov. Rau cov hais tswv yim uas muaj UV-cured, uas cov tswv yim yog polymerized tsis yog absorbed, cov ntaub ntawv thermal tshwj xeeb yuav ua tau zoo dua vim tsis muaj cov dej uas nyob hauv ntaub ntawv. Tsis tas li ntawd, rau cov digital presses uas siv toner—uas siv cov toner dry uas tau txiav los ntawm lub zog—cov teeb meem ntawm cov adhesive yog qhov txawv ntau.

Cov ntaub ntawv uas tuaj yeem siv rau hais tswv yim yog qhov zoo tshaj plaws rau cov chaw ua haujlwm uas ua ntau yam hais tswv yim aqueous, tshwj xeeb rau cov ntaub ntawv uas muaj cov tswv yim ntau heev. Qhov tseem ceeb yog qhov zoo tshaj plaws rau cov chaw uas tau pom cov lamination failures ntau dua rau cov hais tswv yim thiab tau txiav tawm tias tsis yog qhov cuam tshuam los ntawm cov neeg siv thiab tsis yog qhov cuam tshuam los ntawm cov khoom siv.

Qhov tsis zoo ib qho uas yuav tsum nug: cov ntaub ntawv uas muaj qhov ceev ntau dua yuav tshwm sim rau qhov kev pheej xwm ntawm qhov ceev ntau dua. Qhov ntaub ntawv uas pab txhais tau zoo rau hauv qhov ceev 90°C yuav tshwm sim rau qhov ntaub ntawv yuav tshwm sim rau qhov ceev ntau dua 60°C rau hauv cov khoom uas tau txais lawm. Rau cov khoom uas yuav tsum nyob hauv qhov ceev ntau dua—los ntawm cov roj ua hauv lub siab los ntawm cov lus qhia hauv qhov chaw nyob ntawm lub tsev—qhov kev sib thim no yuav tsum nug kom zoo.

Kev xaiv cov ntaub ntawv

Cov ntaub ntawv yog qhov tsuas yog qhov peb puag qhov. Kev sib xws ntawm cov ntaub ntawv, ntawm cov ntaub ntawv, yog qhov tswv yim li cas li qhov kev xaiv qhov ntaub ntawv. Cov khoom uas xaiv cov ntaub ntawv rau qhov kev xaiv cov ntaub ntawv yuav tshwm sim rau qhov tsis zoo uas tshwm sim los ntawm cov neeg xaiv cov ntaub ntawv tsis zoo li cas li qhov ntaub ntawv uas muaj kev sib xws.

Cov neeg ua khoom uas muaj kev sib thim yuav pab tau cov kev daws teeb meem uas muaj kev sib thim—kev daws teeb meem rau qhov ntaub ntawv, kev daws teeb meem rau qhov ntaub ntawv, thiab kev daws teeb meem rau qhov ntaub ntawv rau txhua qhov kev ua khoom . Cov lus no txhais tias cov ntawv pov tseg uas ua haujlwm zoo rau lub sijhawm ua haujlwm yuav tsum yog cov ntawv pov tseg uas tuaj rau hauv lub khaubnciag tom ntej. Cov ntawv pov tseg ISO 9001 yog qhov tseem ceeb rau kev pab txhawj xeeb, tab sis qhov uas ua rau nws nyob npaum dua yog kev txaus siab ntawm cov thawj tswv ntawv pov tseg rau kev coj ua haujlwm thiab kev pab ntxiv.
