What settings are you using for Color Input in Fiery?

[tngcas]

For those of you who are using Fiery, what are your default settings on this screen and why did you choose them?

For those of you who are using Fiery, what are your default settings on this screen and why did you choose them?

Lot going on here.
Sources? Per your 'best' workflow results. (I expect pushback on this)
Embedded profiles? Not usually.
Intents? Per your 'best' workflow results. (I expect pushback on this)

We saw minor differences w/sources-intents between machines.
Choose the best and stick to it for that machine !

Embedded profiles are a disaster waiting to happen when your client is clueless. (But it looked great on my screen/printer !)

We have a persistent problem with one of the canon printers (out of four we are running) where everything is printing with a tint of pink. It’s not just one customer’s file. Canon techs have gone over the machine and say there’s nothing wrong with it. They’ve reloaded fiery software multiple times and recalibrated. They’ve tried to blame everything from paper to lighting to specific customers.

We’ve always used the GrayCol profile but I realized if I turn it to Bypass Conversion the pink tone goes away so now I’m questioning our entire workflow.

An overall tint on the sheet sounds like a rendering intent issue rather than a problem with the ICC Profile
If your intent is not set to Perceptual, change it and see if this removed the background tint, which I suspect is the colour management attempting to simulate paper colour.

Calibration.

The machine has been calibrated to death at this point. I had the techs come calibrate it themselves and they sent canon’s fiery expert. And we tried using a new spectrometer as well and new white plate.

I’ll give changing it to perceptual a try tomorrow. It just seems like a bad idea to leave it on bypass conversion. There’s a point where too many options make this whole house of cards tricky to diagnose.

I would use the following settings:

RGB:
RGB source = sRGB
Use RGB embedded profiles = Yes
RGB rendering intent = Relative BPC or Perceptual (depending on the printer profile, papper etc)
Print RGB gray using black only = Off

CMYK:
CMYK source = Your preferred house standard
Use CMYK embedded profiles = No
CMYK rendering intent = Relative
BPC = Yes

Grayscale:
Grayscale source = Dot Gain 15%
Use Gray embedded profiles = No
Grayscale rendering intent = Relative
Print gray using black only = Text/Graphics/Images

What are you using for your Output Profile?

Are you calibrated for coated and uncoated G7? I had an issue with this the other day where my coated G7 profile was completely oversaturated and running pink. I lied and said it was uncoated and the color cast vanished. I'm kind of considering just only using the uncoated G7 profile since the coated one seems so terrible. We're on PrismaSync on an IP C10000.

Do you create custom profiles?

Do you create custom profiles?

I did whatever the color specialist had me do and I maintain them. It's a G7 Gracol profile for uncoated and coated.

Does it make sense that I get better matches to the color chart for PMS colors when I choose Bypass Conversion???

It does if you don't have proper color management.

What screen/setting has the by-pass conversion?

This window here:

I usually keep this on Gracol, but our new C7500 Ricoh which has been profiled was running a job with PMS 185C and I noticed the red looked slightly less intense than the color book. Turning this setting to Bypass Conversion made it a perfect match to the Pantone Book.

Look in Imageviewer to see what you output values are for that spot color, then you know what values to put in Spot Pro for your output profile in case you wanted to assign a CMYK source profile for managing other elements in the print job.

But the CMYK source profile should not be affecting the values in the Pantone library. I would be reporting that to Fiery and see what they say. Does choosing Default in the Use spot group: make any difference?

Default didn't seem to make a difference. Bypass was the best. Oddly though, I ran another job that had PMS109 and it was way off when I chose Bypass, but spot on with my normal settings. Makes me think PMS185 may be a fluke.

That is why I suggested updating the values for that spot color in for the output profile with Spot Pro. For what ever reason Fiery stores the spot library output values in the output profile. I always thought that was a bit strange because I have never seen any wide format RIP do that. Don't know if the present version XF now does that or not. You can always use the print sample and adjustment feature in Spot Pro to set the specific spot color output values. But be aware that you need to choose the output profile when doing that. The current version of Spot Pro now lets set those values for other output profiles as well.

With differences like this it is always interesting to use Imageviewer to check what the output values are.
