1. Kev npaj ua ntej
Cov cuab yeej uas xav tau: Cov qauv ntsuas ntsuas nrog 0.1mm cov kab ncaj nraim + crosshair alignment marks + 1mm dot spacing, flat blank printing substrate, 40x magnifying glass, vernier calipers/feeler gauge.
Kev npaj ua haujlwm: Khiav lub tshuab ua haujlwm rau 15 feeb kom sov nws. Ua ntej, kho lub tshuab thav duab kom muaj qib, thiab ntxuav lub rooj thiab kis tau tus mob ntawm txhua tus cwj mem los yog cov khib nyiab.
2. Static Positioning Accuracy Test (Basic Accuracy Verification)
Manually align the first print and print the first sample marked "Thawj Tshooj";
Rov pib thiab nres lub tshuab 10 zaug, rov- khiav lub tshuab mus rau qhov chaw ua haujlwm tom qab txhua qhov pib thiab nres, luam tawm ib qho qauv rau txhua qhov;
Sib piv cov crosshair sib txawv ntawm tag nrho cov qauv nrog thawj tsab xov xwm siv lub iav magnifying: tus qauv siv tau yog txhua qhov sib txawv tsawg dua lossis sib npaug ntawm 0.02mm.
3. Dynamic Continuous Production Accuracy Test (Core Verification in Actual Production): Teem cov khoom siv rau nws qhov kev tsim khoom txhua hnub thiab txuas ntxiv luam tawm 100 cov qauv yam tsis muaj kev hloov kho thaum lub sijhawm ua haujlwm.
Xaiv 10 tus qauv kawg thiab sib piv nrog thawj daim, ntsuas cov qauv sib txawv ntawm qhov sib txawv nrog calipers.
Kev lees txais: Tsis pub ntau tshaj ib tus qauv yuav tsum muaj qhov sib txawv> 0.05mm; txwv tsis pub, qhov tseeb stability tsis yog raws li tus qauv.
4. Multi-Color Overprint Cumulative Accuracy Test (Multi-Station Verification): Rau ntau-xim tshuab luam ntawv, nruab ib 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 ua tiav tag nrho cov chaw nres tsheb, soj ntsuam qhov pom tseeb ntawm tus qauv overprinted: clear overprinting uas tsis pom tseeb misalignment ntawm crosshairs qhia tau hais tias qhov cumulative raug ntawm txhua qhov chaw nres tsheb yog txais; txwv tsis pub, nws yog qhov tsis txaus ntseeg.
5. Table Parallelism Auxiliary Test: Ntsuas qhov sib txawv ntawm txhua lub rooj thiab cov kev taw qhia kev tsheb ciav hlau nrog lub ntsuas ntsuas. Qhov sib txawv ntawm Less tshaj los yog sib npaug rau 0.03mm ntawm txhua txoj haujlwm tau txais. Qhov sib txawv ntau dhau qhia tau hais tias lub rooj deformation, uas yuav cuam tshuam ncaj qha rau kev luam ntawv.
