1. Kev Npaj Ua Haujlwm
Npaj ib qho kev tshuaj ntsuam xyuas nrog cov kab zoo, cov kab me me, thiab cov cim kab sib dhos. Cov qauv yuav tsum suav nrog 0.1mm cov kab zoo thiab 1mm spaced me me dots kom yooj yim pom kev ntsuas ntawm kev sib txawv ntawm qhov sib txawv. Npaj ib lub tshuab luam ntawv tiaj tus (piv txwv li, daim ntawv txiav dawb) thiab luam ntawv muab tshuaj txhuam.
2. Static Single-Point Alignment Test (Basic Accuracy)
Manually ua kom tiav cov txheej txheem kev sib raug zoo thiab luam thawj tus qauv, kos nws li "First Article".
Rov pib thiab nres lub tshuab 10 zaug, rov qab mus rau tib qhov chaw nres tsheb tom qab txhua qhov pib thiab nres, thiab luam tawm lwm tus qauv.
Sib piv qhov sib txawv ntawm crosshair ntawm 10 cov qauv thiab thawj tsab xov xwm siv lub iav tsom iav. Yog tias qhov sib txawv tsis tshaj 0.02mm, qhov tseeb qhov chaw zoo li qub tau txais; kev sib txawv ntau dhau qhia tias tsis muaj tseeb.
3. Nruam Dynamic Printing Test (Qhov tseeb ntau lawm, Qhov tseem ceeb tshaj): Teem cov khoom siv rau nws cov khoom siv ceev ceev thiab luam tawm 100 cov qauv tsis tu ncua tsis tas yuav hloov kho.
Sib piv cov qauv 10 kawg nrog rau thawj daim: ntsuas cov qauv sib txawv ntawm qhov sib txawv siv tus pas ntsuas lossis caliper.
Kev Txiav Txim Siab: Yog tias qhov sib txawv tshaj 0.05mm rau ntau tshaj ob qhov qauv, nws qhia tias tsis txaus qhov tseeb ruaj khov tom qab ua haujlwm ntev - lub sijhawm ua haujlwm thiab tsis tuaj yeem ua tau raws li qhov xav tau ntawm cov khoom loj.
4. Multi-color Overprinting Test (Multi-chaw nres tsheb Kev Tshawb Fawb Qhov Tseeb):
Yog tias cov cuab yeej siv ntau - xim qauv, qhov tseeb ntawm txhua qhov chaw nres tsheb yuav tsum tau txheeb xyuas:
Txhim kho tib lub tshuaj ntsuam xyuas ntawm txhua qhov chaw nres tsheb thiab rov luam dua tus qauv qub ntawm txhua qhov chaw nres tsheb.
Tom qab tsis tu ncua luam ntawv los ntawm tag nrho cov chaw nres tsheb, saib seb qhov kawg overprinted qauv yog qhov muag plooj thiab seb lub crosshairs yog misaligned: qhov clearer lub overprint, qhov zoo dua qhov cumulative raug ntawm txhua qhov chaw nres tsheb.
5. Kev ntsuas qhov tseeb nrog cov cuab yeej tshaj lij (xaiv tau, Kev Ntsuas Kev Ua Haujlwm) yog xav tau daim ntawv qhia meej meej, cov cuab yeej tshaj lij tuaj yeem siv rau kev sim:
Siv lub colorimeter thiab spectrophotometer los ntsuas cov xim density uniformity ntawm cov ntawv luam tawm los txiav txim qhov tseeb xim; Siv lub ntsuas ntsuas gloss los ntsuas qhov sib xws ntawm qhov sib xws ntawm cov khoom luam tawm los pab tshawb xyuas qhov tseeb ntawm kev luam ntawv.
