Learn How to Run a Print Job

Open ChromaPress

The first window of ChromaPress lists jobs that have been created in ChromaSpec. The list includes the color number, group(s), and date of last modification for each job. The jobs that appear in this table are determined by the group(s) assigned to this particular ChromaPress user. A user assigned to the Danvers group will only see Danvers jobs.

To show jobs that have already been run, check off the box located in the upper left corner of the window. A 5th column titled “Scans” will appear in the job list table.This tells you the number of scans contained within each job. A job with scans cannot be edited in ChromaSpec.

Icons at the bottom left corner of the screen allow you to run a job (Run a Job) or refresh the list of jobs (Refresh List of Jobs).

A search bar at the top left corner of the page allows you to search the job list by job name. For example, a search of “jim” will yield all of the jobs that contain the word “jim” in their name.

The “Filters…” button, located at the top left corner of the page, allows you to search the job list by device, color number, groups, and/or date of last modification. Click “Filters…” to open up the “Filters” window. After selecting the desired filters, click “Apply.”

Run a Job

(1) Double click on the job or select the job with a single click and then click the Run a Job icon in the lower left corner of the screen.

(2) A window titled “Job: [Job Name]” will appear. This window includes an “Info” tab and a “Measure” tab. First, take a look at the “Info” tab. This tab shows the pressman the job name and the available job fields. The job fields shown are fully customizable in ChromaAdmin. Values are entered into job fields during the creating of a job in ChromaSpec.

In ChromaPress, job fields give the pressman information. This might include the job name, customer name, and the type of stock. This can help to ensure the pressman is running the proper job with the correct materials. For example, you want to make sure you don’t use your own stock when the stock is designated as “Customer Supplied.”

The “Info” tab also shows the color standards that were chosen in ChromaSpec as well as measurement info and whether or not ColorDrive is enabled.

(3) Click over to the “Measure” tab. Click “+” to execute a new scan. You can work in spot mode or scan mode with Techkon devices.

(4) A “Techkon ColorEnsure™” Box will pop up. This feature makes sure the instrument settings correspond to the job specifications. If the instrument is taken away, and the measurement condition or another specification is changed, Techkon ColorEnsure™ will trigger an alert. Techkon ColorEnsure™ is included with ChromaQA free of charge. By default, it is always running.

If Techkon ColorEnsure™ detects a problem, click “Yes” to automatically reconfigure your device. It will now be properly setup to run the current job. If you click “No,” the scan will be cancelled.

(5) When the scan is complete, the “Measure” tab will populate with measurements and charts. The first tab under “Measure” is a dashboard. The dashboard view is customizable. Use the drop down menus located at the top left of each quadrant to choose what charts should be displayed. The dashboard should contain the 4 charts you care most about.

Note that you can hover over some charts to see additional information. For example, hover over the “Solids: Delta D” graph to see reference D, measured D, and ΔD for each patch.

(6) Categories relevant to the current job are displayed in tabs next to the dashboard.

In the following example, the categories relevant to our job are solids, tints, G7, and substrate. Click over to these categories to see additional information and charts.

Solids Tab:

The first option is a full table of information about your solids, including patch, name, reference L*a*b* values, measured L*a*b* values, ΔE, ΔD, ΔL, Δa, and Δb.

Click on the “Delta E” option to see a bar graph of the current ΔE’s as well as Techkon InkCheckⓇ recommendations. Techkon InkCheckⓇ gives specific density adjustments to lower your ΔE. Below each listed adjustment is the current ΔE, and below each current ΔE is the improvement in ΔE that is expected to occur from the density adjustments.

Hover over the graph to view reference Lab, measured Lab, and ΔE.

Check the box located at the bottom left corner of the screen to visually see the impact Techkon InkCheckⓇ density adjustments can have on your ΔE.

Click on the “Delta D” option to view a bar graph of current ΔD’s.

Hover over the graph to view reference D, measured D, and ΔD.

Click on the “Spider/Gamut” option to view the measured and reference hue gamut as well as the linearity of tints.

Click on the “Chroma/Hue” option to view how well your scan is matching your targets.

Click on the “Curves” option. Use the drop down menu in the upper right corner of the screen to view the spectral curves for each color.

Tints Tab:

The tints tab displays a table of information about TVI.

Click on the “TVI” option, located in the left menu of the tints tab, to view TVI curves for black, cyan, magenta, and yellow. To the right of the graph, check boxes allow you to decide which curves will appear on the graph.

Additional categories are organized similarly to the solids tab and tints tab. Depending on the contents of your job, you may have tabs for solids, tints, overprints, G7, substrate, and score card.

The score card tab is where the score card system gives your job a weighted score that tells you whether or not your job passed or failed. Passing/failing is determined by the minimum passing score assigned to your job in ChromaSpec. The score range is set up in ChromaAdmin.

(7) Icons at the top of the page allow you to delete a scan (Delete a Scan), set the OK Sheet (Set the OK Sheet), end make-ready and flag the scans for production (Flag for Production), add notes (Add Notes), toggle between L*a*b* and L*C*H* (Lab LCH Toggle), export scan (Export Scan), export job (Export Job), and save job (Save Job).

Flag for Production

When you start using the program, we assume that you’re in make-ready mode. When you are ready to get out of make-ready mode, click the flag icon (Flag for Production).

Future scans will be flagged for production.

In ChromaReports, you can use the flag feature to filter out make-ready scans. This allows you to create trend reports that only use production scans.

OK Sheet

If you’re having trouble meeting your original standards, the OK Sheet can help. To use the OK Sheet, click the target icon (Set the OK Sheet). This resets your job with a new set of aim values.

When you click on the OK Sheet icon, a window will open to ask you whether or not you’re sure you want to change the color standard values for this job. Click “OK.”

Your job will now have a new set of aim values. Check the dashboard to see how your metrics changed

Note that the OK Sheet is configurable. The feature can be allowed or locked in ChromaAdmin.

Add Notes

Click Add Notes to add notes to your job.


Click the (Run a Job) icon to run a job.

Both ColorDrive and non-ColorDrive jobs have an “Info” tab and a “Measure” tab. Both ColorDrive and non-ColorDrive jobs can also have sub tabs for solids, tints, gray balance, substrate, etc.

ColorDrive jobs are unique in that their Measure tab has a special ColorDrive sub tab.

When you click over to the ColorDrive sub tab, you will see a set of scores.

By default, these scores are set to automatically generate after each scan. This setting is signified by the lighting bolt icon (Automatically Score After Each Scan) located at the top right (to the right of the “Running” score). To turn this setting off, click on the lighting bolt icon. The icon will now have a red line through it (Automatically Score After Each Scan).

The Recalculate Scores icon allows you to recalculate scores after you have already executed a scan.

In the following example, we have executed 1 scan. This is identified by the title “Scan #1” in the upper left corner of the screen. Notice that “Scan #1” is located in a drop down menu. Subsequent scans will populate this drop down menu.

ColorDrive scores are generated for one scan at a time. Use the top left drop down menu to switch between scans.

Notice that there are “Family Scores,” located at the right. These are calculated from individual color scores. Individual color scores are located in the central grid. For example, the ΔE2K 100 Process for K is 4.50. The  ΔE2K 100 Process for Cis 3.00. The  ΔE2K 100 Process for M is 2.00.

The individual scores in a row contribute to the Family Score located to the right of that row.

ColorDrive uses a special algorithm to convert the individual  ΔE2K 100 Process scores to the Family Score of 3.13. This populates a box at the top left (to the right of the ColorDrive logo).

ColorDrive uses another algorithm to convert the Family Scores into a single Running Score. This is located to the right of the Family scores. By default, the individual scores, Family Scores, and Running Score are automatically calculated following each scan. Click on the lightning bolt icon (Automatically Score After Each Scan) to turn this setting off.

Additional options are located in the left menu of the ColorDrive sub tab.

First, click on “Info.” This is where you will enter measurement information which will be sent to ColorDrive. These Info fields are set up in ChromaAdmin.

The next option is “Reg.” This is where you will visually select the registration quality of your colors. Your color standards are displayed at the left. To the right of the standards are drop down menus so that you can select a score for each standard. The score range is 1 (Fail) to 5 (Excellent). A scoring guide is located at the right.

The next option is “Visual.” This is where you score the overall visual appearance of the product. The score range is 1 (Fail) to 5 (Excellent). If you choose a score less than 5, you must identify the defects that lowered the score. A list of potential defects is located below the overall appearance score drop down menu. To identify defects, check the relevant boxes. Notice that the list of defects is organized into sub tabs. Click through each of these sub tabs to see each possible defect.

Your selected defects will appear below defect list.

The last option in the left menu is “Opacity.” Enter the opacity of your substrate as a percentage.

Click the Recalculate Scores icon to calculate a “Final Score.” The Final Score will take into consideration the Family Scores as well as Visual and Registration Scores. The Final Score, located at the top right, replaces the Running Score that was calculated earlier.

Repeat this process for any remaining scans.

Note – As many as 7 attributes can be used to calculate the Final ColorDrive score. Jobs don’t often use all 7 attributes. It depends on the requirements Schawk! sets for a particular job. These requirements are identified when ChromaQA validates the ColorDrive job during its creation in the ChromaSpec module. ChromaPress will only display the necessary attributes, so do not worry if you don’t see all 7 attributes.

When you have finalized each scan, click the Submit to ColorDrive icon to submit the job to ColorDrive.

You can make changes to Info, Reg, Visual, etc., after you have already submitted your job. Click Recalculate Scores to recalculate the job’s score and then click Submit to ColorDrive to resubmit the job to ColorDrive.
