Simulated Process Screen Printing in Canada

Simulated process screen printing is an advanced technique that uses 4-8 spot colour separations with halftone dots to recreate photorealistic images and complex designs. Unlike traditional screen printing that uses solid colours, simulated process creates the illusion of unlimited colours through carefully separated spot colours and halftone patterns.

At T-Shirt Elephant, our simulated process expertise has been refined since 2012, making us Canada's leading provider of photorealistic screen printing. Our team of 75+ professionals specialises in complex colour separations and precise halftone applications that bring photographs and detailed artwork to life on fabric.

How Simulated Process Works

The simulated process begins with analysing your photographic image and breaking it down into 4-8 key spot colours. Each colour is printed with specific halftone angles (typically 15°, 45°, 75°, and 105°) to prevent moiré patterns and create smooth colour transitions. The dots vary in size to simulate different tonal values, creating the appearance of full-colour printing.

Critical to the process is the underbase white layer, especially when printing on dark garments. This white foundation ensures colour vibrancy and prevents the garment colour from affecting the final result. The underbase is printed first, followed by each spot colour in precise registration.

Colour Separation Expertise

Our skilled separators use specialised software to analyse each image and determine the optimal colour breakdown. They consider factors like:

• Dominant colours in the image
• Flesh tones and skin colour accuracy
• Shadow and highlight details
• Garment colour interaction
• Print order sequence for best results

The most challenging aspect is creating realistic flesh tones for portrait work. This typically requires a dedicated flesh tone base, often combined with yellow, magenta, and other accent colours to achieve natural skin reproduction.

Advantages Over CMYK Printing

While DTG printing uses CMYK process colours, simulated process offers several key advantages:

• Superior opacity on dark garments
• Better wash durability than water-based CMYK inks
• Vibrant colour saturation that doesn't fade
• Cost-effective for medium to large runs
• No white ink limitations found in CMYK processes

Technical Considerations

Successful simulated process requires precise halftone angles to avoid moiré patterns. Standard angles include:

• Black: 45° (most critical angle)
• Magenta: 75°
• Yellow: 90°
• Cyan: 15°
• Additional colours: 30° and 60°

Line screen frequency typically ranges from 45-65 LPI (lines per inch) depending on the mesh count and ink type. Higher frequencies provide more detail but require finer mesh screens and precise registration.

Simulated process screen printing excels in specific applications where photorealistic reproduction is essential. Here are the most popular uses:

Photography and Portraits

Memorial shirts and tribute apparel benefit greatly from simulated process. Family portraits, graduation photos, and special occasion images reproduce with stunning clarity and emotional impact. The technique's ability to handle flesh tones makes it ideal for portrait work.

Band and Music Merchandise

Album artwork and promotional designs often require complex colour reproduction that simulated process delivers perfectly. Concert merchandise, tour shirts, and band photography print with professional quality that matches retail expectations.

Detailed Illustrations and Artwork

Complex artistic designs with multiple colours and shading effects work beautifully with simulated process. Vintage artwork, detailed illustrations, and artistic photographs that would require 8+ spot colours in traditional screen printing become economically viable.

Sports and Team Photography

Team photos, action shots, and sporting event imagery reproduce with excellent detail. Custom jerseys and team apparel benefit from the durability and wash resistance of simulated process printing.

Corporate and Promotional Items

Company logos with photographic elements, product imagery, and detailed brand artwork work well with simulated process. The technique allows complex corporate designs to be reproduced cost-effectively on custom t-shirts and promotional apparel.

What Doesn't Work Well

Simulated process isn't ideal for every application:

• Simple logo designs - Traditional spot colour printing is more cost-effective
• Small print sizes - Halftone dots become visible and muddy
• Very fine text - Letter quality suffers with halftone printing
• Single-piece orders - Setup costs make it uneconomical for small quantities
