Simulated process printing is an enhanced version of normal printing where you simulate the look of the true color. Thus, it is a four color printing process that uses opaque inks and certain color separation techniques specific to its application areas. A true four color process printing includes using CMYK to produce a photo-realistic image. Contrary to simulated process printing that includes six, eight, or more color separations.
It is necessary to have a print color mixing machine, which can mix colors in your home for printing high quality, virtual process designs.
Why Should we use Simulated-press printing instead of the four-color process in screen printing?
The four-color process was developed primarily for printing on white backgrounds and process
inks are transparent, making it difficult to print on dark-colored garments. Simulated-process jobs require more screens, but the outcome is stunning.
Most screen printers are well-versed when it comes to printing vector T-shirt art, but a smaller percentage are proficient at printing simulated-process designs.

This is because there’s a learning curve and more attention needs to be given to art preparation and screen making.
What if you work from a photo?
T-shirts were once a digital printing operation, an art perfected by just a few screen printers. Such figures are now increasing as decorators use Adobe Photoshop and applications for color differentiation.
The cycle starts with a snapshot of the graph to be displayed in high resolution. Using the color recognition program to isolate the film or computer screen (CTS) colors until the file is imported into Photoshop.

The color channels or layers on the computer monitor showing 8 or 9 separations, representing all colors, can be visualized after the completion of color separation.
Your picture may also be a more noisy yellow than the regular PMS 122. So you should modify the color profile should to a louder yellow profile.
Further, it is easier to display your image if you are watching the composite picture on the computer.
In Photoshop, you can do it manually or use the software’s drop-down feature. If needed, the green will be yellow and blue; in Photoshop, I usually will. Usually, the turquoise is dark.
Selection of a Screen:
Retensionable aluminum and static aluminum stretch and instruction collection are the most popular frames to use it in the simulation phase printing. You should use a yellow mesh should. And increase pressure upto 25 N / cm, or higher in the 230-305 mesh count range.
This particular mesh color is ideal for halftone printing since the amount of light dispersion induced minimizes by screen exposure. The traditional method for choosing the correct mesh count for halftone prints is to subtract the dot line count by four and then to the next usable mesh count.
RIP Softwares with Halftoning:
A 55-line elliptical marker with angles set to 61 degrees for simulation research. It is a typical marker scale to use for textile screen printing. You need to write and highlight the rest of the modeling workstations with a white frame. Both the corresponding shades are then written on the surface wet-on-wet.

After segregating the picture, the following step is to show the separations on the video or to submit them to a CTS system until you see it.
The RIP must translate details from artwork files to a halftone and transmit this data to the inkjet printer or CTS for output.
The RIP is a computer-specific processor (RIP) for transferring the image to a rasterized halftone picture. Several RIP software bundles, including AccuRIP, Wasatch, FastRIP and more are available.
With an inkjet printer, the films automatically isolate. Polyester film — sheets or rolls — and matched with a standard pin registration system on the displays. The following step is to screen the view.
It is important to use an Exposure Calculator at first to dial correctly during the halftone exposure.
Several types of exposure calculators are available, including grayscale 21-step, filter-type, and step-wedge exposure calculators.
Older analog exposure systems utilize a metal halide lamp that can reveal displays within 2-3 minutes, whereas modern LED exposure systems on the market will show as soon as 8-50.
You will save from pain with an exposure calculator Multiple screen exercises to get a good exposure.

How to Cure the Finished Print?
It is necessary to use a donut sample regularly to check the temperature of the printed ink when it passes through the dryer. The standard plastisol ink curing temperature is 320 / F.
For prints on 100 % polyester fabrics. The new low cure plastisol inks only require temperatures within the range of 275 to 300 F.
Note that you should obey the prescribed temperature of your ink supplier for the drug you use. Another way for simulated processes to start with screen printing is to buy process clip art from a branch of industry supplier.
You can literally generate the positives for the video, open the screens, and go straight to the news.
You will boost the overall comprehension of the program by printing digital operation clip art. Printing simulation process designs can allow your company to differentiate itself from your competitors and to develop a reputation as best in the field.
We want more complicated artwork. With a lot of detail in it and a lot of colors thus simulated process printing should be a necessary part of your screen printing business.
It can be a nice looking complex print that brings in a lot of money.
