Special Inkjet Considerations

Quality May Different on Different Paper Grades OEM ink 3rd party ink Same printer (Canon), same driver settings... = Photo glossy Plain paper =

Quality May be Different on Different Paper Brands Canon printer Canon paper Canon printer Epson paper Printed using the same printer, same 3rd party inks, same driver settings… but on different paper brands (same grade, both coated)

Measurement Tools Scanner Handheld Motion system Your microscope Multi-angle camera system Different hardware configurations for different applications. All configurations use the same software X X i

Measurement Tools Different hardware configurations allow you to use measurement tools in all stages of product development including benchmarking (competitive analysis), R&D and manufacturing. Research & Development Production (QA/QC) Benchmarking X X i

Portable System: ImageXpress ,[object Object],[object Object],[object Object],[object Object],[object Object],For manual, high-magnification image analysis

[object Object],[object Object],[object Object],[object Object],[object Object],For manual, large field, portable image analysis Wide Field of View Portable System: iXmax

Scanner-Based System ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],Automated and interactive image analysis

Manual Motion System ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],For manual, low-volume, high-magnification image analysis

Full-Motion System ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],For automated, high volume high-magnification image analysis

Note on Calibration ,[object Object],[object Object],[object Object],[object Object],Calibration is critical to image quality system performance

Upgrade Path Scanner or manual motion Motion system Handheld system All of our hardware configurations use the same software.
