# Print Control

**The printing controls are carried out using charts, standardized control ranges or personalized in CMYK, RGB or spot colors.**\
\
Standardized control ranges are published by professional bodies such as IDEAlliance, Ugra, Fogra, ECI and BvDM or provided by software publishers, such as EFI, GMG, etc... \
They are sometimes free but most often paying (La Fogra e.g.). These are mainly used in the field of Graphic Arts to control the proofs printed according to ISO 12647-x standards

### The Print Control module

The aim of this module is to:

* Check the B.A.T.s (Good To Draw) in order to validate compliance with reference standards.
* Check the stability of your printer to avoid unpleasant surprises when printing.
* Check the quality after a calibration operation.
* Check the uniformity of printing between several printers.
* Control the reproduction of your direct colors (PANTONE color charts, vinyl color charts, etc...)
* Control the test targets that will be used for the characterization of your offset printer e.g.

### The first step is to create the reference range

To generate your chart you can choose between creating a chart in RGB, CMYK or done with spot colors.

This module will allow you to create control ranges from colors from:

#### - A range of controls to Graphic Arts standards, to verify compliance with the proofing standards.

{% content-ref url="/pages/-Lk\_VvI-AYk68y0iA3-z" %}
[Create a reference for Proof](/quality-control/create-a-reference-print-control-target.md)
{% endcontent-ref %}

{% content-ref url="/pages/-MHg\_08VEtMcKqABoU3x" %}
[Create a reference from the values of an imported range](/quality-control/untitled-2.md)
{% endcontent-ref %}

#### From a measurement made on a reference print, to monitor the stability of a printer e.g.

{% content-ref url="/pages/-MHgZuOMy6lnHMyV1hfn" %}
[Create a reference from a printed Mediawedge](/quality-control/untitled.md)
{% endcontent-ref %}

#### From a standard range, to carry out a more precise control or to control the ranges intended to be averaged to characterize an offset printer e.g.

{% content-ref url="/pages/-MHgZz5LlJZ6rraoVhk8" %}
[Create a reference from a printed chart](/quality-control/untitled-1.md)
{% endcontent-ref %}

#### A color chart of direct colors, to control the reproducibility of the colors of your PANTONE color charts e.g.

{% content-ref url="/pages/-MHg\_2-Vq9UkD6QDBcZw" %}
[Create a reference from a spot color swatch](/quality-control/create-a-reference-from-a-spot-color-swatch.md)
{% endcontent-ref %}

#### From a color table, to customize and choose the colors you want to control.

{% content-ref url="/pages/-MHg\_2UrNDczF4gX3odb" %}
[Broken mention](broken://pages/-MHg_2UrNDczF4gX3odb)
{% endcontent-ref %}

### The second step is to measure the range generated previously

The results of this measurement can be used to validate the printed result using standard or personalized tolerance values. \
This module makes it possible to measure and validate standardized CMYK ranges, RGB ranges and IT8 test charts, and all other test charts produced using the Coraye reference creation module.\
\
**Each control measurement will be added to the reference file in order to keep a history of the measurements made to monitor the drifts of your printer.**\
This module can be very useful to decide if you need to redo a new calibration (for example: if you change the paper emulsion that you are accustomed to using) or to help you make a technical diagnosis in the event of a problem. with your printer. So you can guarantee your customers the regularity of your impressions.

### The different types of ranges that can be used with Print Control:

#### 1) Standard CMYK ranges to control proofs in the field of graphic arts

Coraye offers four types of ranges as standard:

![Mediawedge 72 patches Fogra](/files/-MHX_wbLBaU4UIaETH9V)

![IDEAlliance 84 patches](/files/-MHXa1G4VIC7DXJj2xOM)

![Mediawedge 46 patches Fogra](/files/-MHXa5efSy34uZC4yCT1)

![IDEAlliance 54 patches](/files/-MHXa9D7W_qB5ibcyZhC)

#### 2) RGB ranges to control the stability and neutrality of your prints

Coraye offers two types of ranges as standard:

![Mediawedge RGB](/files/-MHX_ksvKW51UMCo2-oU)

![Mediawedge Grey RGB](/files/-MHX_pu6HfH1pzzt7t3w)

#### 3) The test charts offered as standard in the profiling module for more precise control of your prints.

* ECI2002 CMYK (1539 patches)
* ECI2002R CMYK (1485 patches)
* IT8.7-3 CMYK (928 patches)
* IT8.7-4 CMYK (1617 patches)
* TC 3.5 CMYK (432 patches)
* TC918 RGB (918 patches)
* TC2.83 RGB (294 patches)
* etc...

#### 4) The test charts generated from the spot color tables in order to check the accuracy when reproducing your PANTONES or your other color charts.

{% hint style="info" %}
Spot color control requires the use of a RIP that supports spot color management such as PANTONEs. \
If you use custom spot colors, you must first add the colors you want to check and control, in the RIP color chart.
{% endhint %}

#### 5) Personalized test charts created from Coraye color tables

#### 6) The RGB or CMYK test charts imported in CGATS, IT8, cxf, etc ... formats, for example from the RIPs which control your printers.
