To Rip or Not To Rip
How to know when your design should go into a RIP program…
Maybe the first question that comes to your mind is, “What’s a RIP?” Most screen print designs are one or two colors, or spot color. In other words, they are created without shading or tonality. A large flat area of one color printed the same way across.
However, if you have a detailed design with shading or realistic looking effects, then you will probably have to use halftones to achieve the look you want. Halftones will help to enhance your design’s detail and depth. But halftones also require that make a few digital adjustments to your design before taking it to the press. That process, a “RIP,” is accomplished with Raster Image Processing (RIP) software.
You don’t always need to use a RIP when printing halftones though. There are two ways to create halftones that will allow you to burn and screen print them properly:
Bitmap vs. Rip:
Both of these methods will give you halftones. With a bitmap, you have less control and less detail with your print. With AccuRip you have more control over details, it will look clean, and you don’t have to manually set the greyscale.
Simple right? Below we outline how to accomplish halftones with each method:
Creating Halftones with a Bitmap:
Here’s how to turn a design into a bitmap using Adobe Photoshop:
- Open your artwork in Photoshop.
- Go to Images > Mode > Greyscale.
- A dialog box will pop up saying, “Changing modes can affect the appearance of layers. Flatten image before mode change?” Click Flatten.
- Another dialog will pop up saying, “Discard color information? To control the conversion, use Image > Adjustments > Black & White.” Click Discard.
- Then go to Image > Mode > Bitmap. The Bitmap dialog box will pop up, we left our Output at 300 pixels/inch and Method Use at Halftone Screen, then click OK.
- That will make the Halftone Screen dialog box pop up. We also left our Frequency at 45 lines/inch, angle at 22.5 degrees and shape at Round. Then click OK.
Now you have your halftones!
Creating Halftones with AccuRip:
- Open AccuRip Black Pearl.
- Under the Configure Printer tab, select your printer under the Detected & Supported Printers drop-down menu.
- Under Ink Setup, check the box for Multi-Black.
- We left the defaults under the Configure Halftone tab.
Then just click print and you have halftones!
