How to split CMYK raster colors in CorelDraw

 How to split CMYK raster colors in CorelDraw 

Split 4 (four) CMYK Colors with Coreldraw Manual screen printing is an important part of the screen printing process. Wrong in the color splitting process causes screen printing results that are not optimal, namely colors that miss or create shadows that we don't want. 

Therefore, it is necessary to observe the following steps, 

First you have to have a large resolution image, you can download it on DeviantArt, you can download free or paid images. 

Now open Coreldraw, change the paper size to A3 

File > Import and select the image that was downloaded from Deviantart earlier 

Select the Rectangle Tool (F6), create 4 squares (serves as a benchmark during the screen printing process) 

Select the image and press the P key on the keyboard, so that the position is in the middle. 

Change the image type to CMYK by 

Select Bitmaps > Mode > CMYK Color (32-bit) 

OK, now we're going to start separating the colors and converting them to rasters. 

-Cyan Color 

1. Change/take a picture only the Cyan color 

Choose Effects > Adjust > Tone Curve 

Change Channel to Magenta channel 

Set the Y : curve to 0, while X : leave it alone 

Click Preview 

Change Channel to Yellow channel 

Set the Y : curve to 0, while X : leave it alone 

Click Preview 

Change Channel to Black channel 

Set the Y : curve to 0, while X : leave it alone 

Click Preview 

Click OK 

We've got the color cyan. 

2. Now we will change the cyan color earlier to black and white (grayscale) 

Select Bitmaps > Convert to bitmap 

Then a convert to bitmap box will appear 

Set the Resolution according to your needs (we only use 200dpi) 

Change Color mode to Grayscale (8-bit) 

Tick ​​Transparent Background 

OK 

Cyan has changed to black and white. 

3. Change the grayscale earlier to raster 

Select Bitmaps > Color Transform > Halftone 

Then a halftone box will appear 

In the halftone box, only black will appear, then set the dot tilt to 45 degrees, at Max dot Radius to set the radius point size, fill in 3. 

OK 

If you zoom in, you will see the raster dots. 

Now save the file, select File > Export with the name Cyan 

Or more clearly, see >>> How to save files in Coreldraw 

Done, for cyan 

After Cyan has been saved 

Click Undo (Ctrl + Z) 3 times (to restore the raster, grayscale and cyan images to their original state) 

For the next colors Magenta, Yellow and Black, you just follow the Cyan steps above. 

The difference is only in step 1, 

-Magenta color 

If you want to take the color Magenta, it means cyan, yellow and black, the Y is changed to 0. 

-Yellow color

If you want to take the color Yellow, it means cyan, magenta and black, the Y is changed to 0.

-Color Black 

If you want to take the color Black, it means cyan, magenta and yellow, the Y is changed to 0.
