• It’s better to have durable and long lifetime and warranty to ensure my authority.
• We do have one sheet proof machine from Sino-mv tech and two card inspection systems from you. But we still need an auto sheet inspection system to control the offset printing quality and sometimes we outsource printed sheets and we also need the inspection before warehousing.
• Honestly, I used to work in banknote printing company in Thailand and we’ve cooperated with CBPM-KEXIN to have an online sheet inspection module on our offset print press. It’s too expensive and the maintenance is like a disaster. It’s difficult to ask the print press manufacturer for the fast response for cooperation and the service fee is high. Print press always bend the sheets which influence the camera imaging. So do you have the cost-effective independent sheet inspection system?
• We have card inspection machine from M.B. We’re satisfied with it. But it’s difficult to guide captain to adjust the offset press. Current QC requires the inspection in every important process. So we’re looking for a reliable sheet inspection system after offset printing.
• We’re the plastic card manufacturer and looking for the sheet inspection system. It’s better to inspect layout error, size error, bad registration, printing error, missing, ink cracking, chromatography, chromatic aberration, pearly finish, transparent sheet…
• We have plenty layout products. It’s better to be compatible with various layout and size from 295*480mm to 480*590mm, various thickness from 0.1 to 0.76mm. And switch is better to be fast and easy.
• It’s better to use the same input and output structure with the offset print press.
• We have card inspection machine from M.B. It always takes lots of time for template setting. But our main business is member card and loyalty card which have multiple artwork and layout. Each artwork has small or middle batches. Do you have the printed sheet inspection system with fast template setting within 4-5 mins.
• It’s better to have defect map to display the defect position and main defects
• It’s better to display the defect type of each card
• It’s better to count good cards, NG cards and the rate
• It’s better to record the results in log file and output it for analysis
• It’s better to be faster than 1000CPH
ADVANTAGES
• Multiple layout compatible and easy switch
• Multiple sheet thickness and materials compatible
• No harmful feeding and collecting structure widely used in Heidelberg printer
• Quick template set-up time in 4 mins
• “SuperVision” Smart software ensures simple operation and easy training, displays defects position cumulatively to guide captain to improve printing result by fine tune adjustment.

Q & A before Sales
Q: Who will need the auto large sheet inspection system?
A: Card manufacturer and printing house.
Q: Why do we need the auto large sheet inspection system?
A: As we all know, card manufacturers usually do the card inspection or rely on the print press captains’ experience to control the quality. But manual inspection is unstable, employment and training cost are high. Card inspection can’t inspect printed sheets. Sheet proof machine is a static analyzer which is not consequent and efficient. Online inspection on offset print press is not accurate enough and extremely expensive and its maintenance is complicated. So every card manufacturer are keen to have a independent sheet inspection system to control the offset printing quality. It’ll strengthen the quality control in the key process and reduce the waste of downstream process consumables like inlay, chip and hologram.
Q: What can the auto large sheet inspection system do?
A: Inspect all sheet visual defects like layout error, bad registration, position error, printing error, missing, ink cracking, chromatography, chromatic aberration, fiber, scratch, dirty…
Q: What kind of material can you inspect?
A: Plastic sheet, paper is optional
Q: What’s supported sheet size.
A: Landscape is 540mm. So the max. inspection size is 540mm. Customization is available
Q: We have different size and thickness sheet. Is it available for inspection?
A: Yes, welcome to send us sample sheets for test.
Q: What’s the inspection tolerance?
A: General defects inspection tolerance: 0.067mm² (Contrast<20 Grayscale); Special defects inspection tolerance: 0.25mm² (Contrast>10 Grayscale); Size inspection tolerance: 0.26mm*0.26mm (There must be a mark point in the field of view)
Q: Could you inspect registration, chromatography and chromatic aberration?
A: Yes, but there must be mark points and CMYK marks in the field of view. And it’s better to do white balance for the camera before each batch of inspection to get a good result.
Q: Could you specify the inspection tolerance?
A: Generally, it’s as below:
| Station | Defect Type | Inspection Standard (Larger than the standard can be accurately judged as invalid, the unit is width or length or diameter) | Condition |
