Quote from: Lyzan on November 04, 2015, 12:16:57 PMPress calibration is not an easy job and an expensive undertakings if done correctly according to standard procedure. From your post, I can say that you are not in for standardization-internal or international standards. You just need a "patch" fix. There are two ways you can do this.

1. Forget about any calibration. Just use the page tone adjustment in XMF under signature tab. Here you can adjust page-by-page the 50% value of CMYK in -25/25 increment I think. BTW, I have not tried this feature, but it's there.
2. Remove any linearization curve. Run your test form at norm density that your friend's using. Enter values that you wish base on your test form result in the linearization tab instead of using characterization tab. Here you are compensating the press without regards with any standard norms. It was like you are using an image editing curves, :-)

But then the correct procedure is to follow either PSO or Gracol guidelines.

Thank you Lyzan,

I will just check the tone values against standarts I mean If 40 % CMY are 53 % and K 56 % and also undertones where they are in .
Simply a compansation I will follow, since there are some adjusted values I know someone made them, I will correct after the dot test image against the standard TVI values in the attachment ( which I copied from medienstandard document of BVDM).
Do you have a follow up procedure just for this, I mean to correct the existing tonal value curve values after test print whixh will show the present dot increase status?

With that table, you shall follow PSO guidelines. Here's a brief summary of the guidelines.

1. Standardized your file acceptance and preparation. Emphasize on color management.
2. Linearize your plate. Check uniformity across the plate.
3. Run your test form to find optimum density of the press. Compare color space with 12647-2 requirements.
4. After satisfying yourself on your color space base on your optimum density, run your test form for dot area using the optimum density.
5. Enter the result in XMF characterization. Put all relevant information especially paper and ink information. In characterization, you will have something like - target (from your table) and actual (your reading from your test form).

This is a cycle until you get what you wanted.

Thank you Lyzan for explanation against PSO, for the moment but I had asked short correction procedure ( or how to enter the press TVI values into XMF) in the attached XMF page using the numbers that I attached previously as standard.

Best regards,

Engin

Quote from: prepress2 on October 28, 2015, 08:50:21 AMIt took me a while to wrap my brain around Colorpath but once you do it fairly clear. The "flow" of creating and applying characterization curves is this:
To get from XMF to Colorpath click the color wheel icon on the top bar. This will launch a browser and load the Colorpath interface. You'll need Microsoft Silverlight extension and suggest Firefox.

Select the Characterization tab and create your curve(s) then apply it to the screen sets you want to use it with.
Once that's done go back to the media tab, select the press device you want to apply the curve to, click on either the edit or new button (bottom right). In the window that opens create a new media by selecting the new button at the bottom of the Media Types inset window. Once the media is created check the box next to it to select it. Then below in the Characterization Curves inset window select which curve set(s) you want to apply the curve to. Select the curve from the pop up menu below the list of screen sets and click the Set button.

Then back in the XMF client make sure you change your press device to the new Media Profile in your Job Templates and re-render any existing jobs you want to use that curve on.

I hope this helps, sorry can't grab screen shots atm.

Thank you vey much prepress2 all info are welcomed.
I will keep this aside also.
Best regards,
Engin

Quote from: Lyzan on October 28, 2015, 04:01:18 AMCan you give me the screenshot of Colorpath Sync? My XMF is version 5.5 and the module for press calibration is named Colorpath Organizer. Anyway, I will assume that it's almost the same. Look for the [Characterization] tab in Colorpath.

BTW, are you running linear plate? If not, you can actually use the linearization curve to become your dot gain compensation curve.

//Lyzan

Dear Lyzan,
Actually I wil just make a quick press test to see why dots skin are so reddish ( not plate linearisation I hope for the moment) ? Especially check undertones of M and Y?
Meanwhile I made a quick şnternet check and found exactly what you say, color path organiser page and enter to teh tab xharacterisation.
This week in Turkey, we are in Hollyday and vist my friend next week. I do not know erxactly which version of XMF, but should not be any problem if different version? But I think before 2014.
If you can give me a short procedure how to enter to characterisation tab,then will study before visit him and after the test make right away necessary dot compansation changes.

Quote from: Lyzan on October 25, 2015, 02:35:41 AMThe online help will guide you. I can also guide you, just ask specific question. However, I will assume that you have in-depth experience doing press calibration and characterization.

//Lyzan

Yes Lyzan, more experience doing plate characterisation with KODAK Harmony curves. But as I told my friend has a problem that homan faces looks very reddish in magazine prints and needed my help. I will make a press print with the attachment to see the levels of dot gains and make necessary corrections. He has FUJI XMF Colorflow and I do not kanow where to enter the required corrections of the % tints after press trial then to see the effect of correcetions on the dots.

I made an internet search and found that for XMF, the required part is Colorpath Sync so I asked the user guide of that part to understand the entrance procedure for the % dot corrections into XMF.

Engin

Hi,

I will help my friend to create dotgain compensation curves in XMF.
But I need some knowledge where to enter and found in colorpath part.
Can someone share with me XMF Colrpath user guide?

Engin

Hi,

I need AGFA APOGEEX Color Tune Measure User Guide.
Can someone share it with me?
