How can I use GMG DotProof with 1-Bit files from the CtP-RIP? – GMG Support

For this, you need a GMG medium and a proof standard that contains an MX5 or MXD profile. If you do not have such a profile yet, you can create it with GMG ProfileEditor or GMG OpenColor in a few steps. The important thing here is that the screening data from the profile exactly matches that from the 1-Bit files.

How to create a color accurate halftone proof with 1-Bit files:

Do you already have a proof standard with a matching profile for your 1-Bit files? Please click on the appropriate answer below.

a) No, I have neither a proof standard nor a matching profile.

Please first create an MX5 or MXD profile that contains the same screening information as your 1-Bit files. You can find instructions on how to do this under the following links:

Creating an MX5 profile with GMG ProfileEditor
Creating an MXDprofile with GMG OpenColor

With the new profile, you can now create a matching proof standard as described under b) below.

b) I don't have a matching proof standard, but I already have an MX5 or MXD profile.

Using your profile, you can create a matching proof standard as follows:

From the main menu, choose Database.
Open the tab Proofing Conditions.
Under Printers, select your printer.
Under Media, select your GMG medium.
Under Proof Standard, at the end of the list, click on Add and choose Add Custom Proof Standard....
A dialog opens.
From the menu on the left, choose Properties.
Under Name, enter a name for your proof standard.
From the menu on the left, choose Color Management.
Is your profile an MX5 profile? If yes, please activate the section MX Based.
Is your profile an MXD profile? If yes, please activate the section MXN/MXD Based.
Under DotProof in the appropriate section, select your profile and confirm with Open.... If you see a yellow highlighted warning at the top, you can ignore it.
Click Save & Close.

With the new proof standard, you can now create a GMG DotProof workflow or job as described under c) below.

c) Yes, I already have a proof standard and a matching profile.

With this proof standard you can create either a GMG DotProof workflow or a GMG DotProof job.

How to create a GMG DotProof workflow:

From the main menu, choose Workflows.
Open the tab Overview.
Select the hotfolder for your new workflow.
Right-click on a free space and choose New Workflow... from the right-click menu.
A dialog opens.

If you have not created any hotfolder yet, New Workflow... is grayed out. In this case, please first create a new hotfolder for the workflow by selecting New Hotfolder....
From the menu on the left, choose Input Settings.
Open the tab General.
Under Workflow Name, enter a name for your workflow.
Open the tab Filters.
Under Color Depth (per Channel) Filter), activate the 1-Bit. checkbox.
Under File Format Filter, select the same format that is used by your CtP-RIP.
Deactivate the boxes next to PDF and PS/ General EPS.
Open the tab Merge Files.
Under Rules for Recognizing Separate Files as a Single Image, choose the appropriate recognition for your data.
From the menu on the left, choose Color Management.
Open the tab Proof Output and under Proof Standard, choose the appropriate proof standard.
Under Proof Mode, choose DotProof.
Click Save & Close.

The GMG DotProof workflow has been created. New files in your input folder are now automatically processed according to your configuration.

How to create a GMG DotProof job:

From the main menu, choose Jobs.
Right-click on a free space and choose New Job... from the right-click menu.
A dialog opens.
Choose all the 1-Bit files that belong to the image that you want to print with this job.
Under Merge files, select the same merge pattern that is used in your CtP-RIP.
Under Proof-Standard,select the right proof standard.
Confirm with Open.
The Manual Job Manager opens.
Check if the settings in all tabs are correct.
If you want to print the job immediately, confirm with Print.
If you want to print the job later, confirm with Save & Close to apply all settings and print the job later.
