Title: GretagMacbeth IO device woes
Scott,
I agree with you! I've had same problems with iO and noticed that it is waste of time trying to read test charts printed with 360dpi even with stochastic screening.. I have older EyeOne (rev a) and wonder if newer rev B would handle this better.
Seems that iO is made way too sensitive for reading errors. When iO was first published in GMB web site they mentioned that iO is perfect also for reading fabrics.. I haven't seen any fabric that iO would read. The only way you can read fabrics, is this patch-by-patch tool (at least mine works in Windows DOS prompt).. They also promised to add this function to future releases of PM.. Wonder when this future is??
IMHO, iO is still in "promiseware" state.. Will it never work as promised.. We'll see..
Regards,
Jouni Mustonen
I've recently had some issues with the GMB IO that I thought I might share. While the IO seems like a perfect device for signage and grand format printing (where the use of thicker materials is common) the IO cannot measure the course printing screens that these printers often have. Even though an EyeOne can measure these printer's patches in it's strip reading mode, it cannot when used with the IO. The threshold seems to be right around 8 color printing at 600 dpi.
When I contacted GMB they confirmed this. "The IO generally will not read course line screens - its just the nature of the device." They gave me a beta application that allows the IO to operate in a "patch by patch" mode like the Spectrolino but then we are back to Spectrolino speeds. It looks like signage and grand format users that need a quick device that will handle thick materials should stick with an EyeOne or Pulse.
