![]() Nearly every painter in past centuries was attentive to this axiom, and it’s applicable no matter what the medium, working method or model. There’s a simple principle for depicting beautiful, convincing fleshtones: Alternate warm and cool color temperatures. His portrait of painter Juan Ramírez, Juan (oil on gessoed hardboard panel,14×11), beautifully exemplifies the use of warm and cool fleshtones that Pulido teaches in the classroom. It's just printing normal spot colors separations.Although my primary medium is egg tempera, for many years I studied oil painting with Numael Pulido. Don't worry about screen angles or line frequencies because we Already set those up in Photoshop and as far as illustrator is concerned, it's not printing halftone. Now if you go to print your separations, you will see your four color channels to print. The Image you just placed into illustrator is going to look funky but don't worry about what you are seeing on the screen at this point. Once that new document is open, go to menu "File/Place" and select that EPS file you just made in Photoshop Create a new illustrator file in CMYK mode and setting your art board size to the size of your transparencies you will be printing. Select option single file with color compositeġ1) Now it's time for illustrator. And select format option "Photoshop DCS 2.0" and make sure spot colors is selected The image will look a bit funky on your screen but if you zoom out making the images look smaller, it will look a bit better.ġ0) Next go to menu File/Save As. Repeat this process for the remaining two documents.ĩ) Now your original untitled 1 document should contain all four of your channels. So go to untitled 2 (magenta) document and right click on that process magenta Channel and duplicate it to the untitled 1 (cyan) document. Let's use untitled 1 document as the file we will copy the other channels to. The original, untitled 1 (cyan), untitled 2 (magenta) and so on. Then repeat the whole process for the yellow channel and the black channel.Ĩ) Finally, there will be five documents open in Photoshop. ![]() Click on Color Libraries then select the color swatch Process Cyan then click OK then click OK againħ) Now go back to your original file and right click on the magenta channel and follow the exact same process. This will open another dialogue for you to change the color to process cyan. If you never ever take advice from anyone, take a leap of faith and take my advice on that! If anyone has questions about that statement, I will be more than happy to explain in further detail.ĥ) Now that your image has your Halftone dots, we need to convert the color mode to grayscale then convert again to MultichannelĦ) Now in your channels pallet, double click that channel which should say Black, and rename it to Cyan and enter the value zero in the solidity option then click on the little black Color Square. Always use the same screen angles for each color!! 22.5 degrees is what I use. 305 divided by 5 = 61 <- that value is known as "LPI" (Lines Per Inch)Īfter 28 years in screenprinting, I'm going to share with you one of the most important secrets that most "separators" are not aware of or do not follow. Simply put, take the screen mesh value and divide that by 5 (I prefer 4.73) Let's assume the screen mesh will be 305 (which is standard for four color process printing) so. It is the screen mesh that is going to be used for the screenprinting which dictates the dot size to use on your films. This step is perhaps the most crucial! There is a formula for this which generally must be followed, otherwise the resulting screenprint Will likely contain crazy morei patterns. In the drop down menu select Halftone screen then click ok.Īs a side note, in that dialog window, 300 pixels per inch has nothing to do with the halftone sizes or anything else other than just the file's resolution This will open up your bitmap mode options. To do this, we need to convert the cyan channel to bitmap color mode. Now it's time to create the halftone dots right in the image itself. This will open a new Photoshop document with that new cyan channel you just duplicatedĤ). This will open another dialog box asking where to save this duplicate. ![]() ![]() Now we need to convert the color mode to Multichannel.ģ) Now in your channels pallet, right click on the cyan channel and select duplicate CAUTION: DO THIS ON A COPY OF YOUR ORIGINALġ) If your image in Photoshop is not already in CMYK color mode, convert it now.Ģ) In Photoshop, make sure your channels pallet is visible. Here is the step-by-step process to follow. This process will create you're halftone dots right into the image itself that you will see on your computer screen. Unless your printer is postscript or you are using rip software, your only option to be able to print Halftone separations, is to use Photoshop and convert each channel to bitmap mode.
