In the world of packaging and advertising, roll label printing plays a vital role in product presentation and enhancing visual appeal. Many businesses use roll labels to display product information, strengthen branding, and improve customer experience. This printing method is ideal for various industries due to its high quality, production speed, and flexibility in different volumes. From food and pharmaceutical packaging to cosmetic and industrial products, roll printing has earned a special place in modern packaging processes.
What is Roll Printing?
Roll printing is one of the most widely used industrial printing methods where raw material is fed into the machine in rolls, then printed and cut into various sizes and shapes. These materials may include paper, plastic, metalized films, or other specialty substrates depending on product and industry needs. There are two main methods:
- Heated Roll Printing: Performed at high temperatures for better ink transfer and improved print quality.
- Cold Roll Printing: Performed at lower temperatures, suitable for heat-sensitive materials.
Each method has unique applications depending on material and equipment. Roll label printing employs techniques such as offset, flexographic, digital, and gravure printing, each offering distinct advantages. Since roll printing is continuous, production speed is very high, making it ideal for large-volume, diverse projects.
Applications of Roll Printing
As mentioned, roll printing is widely used in the printing industry for labels, packaging, and product stickers. Due to its speed and quality, it has become a preferred method in many sectors. Here are some key applications:
- Product Packaging: Roll printing is primarily used for flexible packaging in food, pharmaceutical, and cosmetic industries. Materials like plastic, cellophane, and paper are printed with graphics and information, then used for packaging products.
- Product Labels: Roll label printing is common for beverage bottles, dairy products, shampoos, detergents, and other consumer goods. These labels often include brand names, product details, logos, and essential info such as nutrition facts or usage instructions. Durable materials like metalized paper ensure longevity under various conditions.
- Tags and Stickers: Used across industries to produce labels with product specifications, barcodes, serial numbers, and expiry dates. This method enhances production speed, reduces human error, and ensures high accuracy.
Benefits of Roll Printing
| Feature |
Description |
| High Speed Printing |

| Reduced Production Costs |
The continuous process reduces waste and downtime. Lithography provides high precision while saving ink and paper. |
| High Quality and Accuracy |
Roll printing ensures accurate color transfer, consistent tones, and excellent visual quality. |
| Versatility in Substrates |
It allows printing on vinyl, plastic, specialty papers, and other flexible materials, making it suitable for various uses from labels to industrial packaging. |
| Efficiency in Mass Production |
The continuous nature of roll printing makes it an ideal choice for high-volume industries such as food, pharma, and cosmetics. |
Difference Between Roll and Sheet Printing
- Paper Feeding: In sheet printing, paper is fed as separate sheets, while in roll printing, continuous rolls are used.
- Speed: Roll printing also performs folding simultaneously with printing, allowing speeds up to 60,000 prints per hour compared to about 10,000 in sheet printing.
- Double-Sided Printing: Roll printing enables simultaneous double-sided printing, unlike most sheet-fed presses where each side is printed separately.
Post-Print Label Processes
At Nami Naghsh, after printing, several processes are carried out to finish and prepare roll labels with excellent quality. These include hot foil stamping, die-cutting, slitting, and jumbo cutting—each enhancing beauty, precision, and efficiency.
Screen UV Coating
Using high-quality UV silk screen machines, we apply spot gloss, embossing, and glitter UV to enhance your custom labels.
Hot Foil Stamping
Depending on customer requests, roll labels can be enhanced with gold, silver, holographic, and other foils for maximum brilliance.
Die-Cutting
Die-Cutting: One of the most critical post-print processes. With precise equipment, we cut labels into various shapes while peeling off excess material for perfect results.
Slitting
Printed roll labels are separated and counted precisely with slitting machines, then delivered according to customer specifications.
Jumbo Cutting
Using advanced jumbo cutting machines, Nami Naghsh Printing Complex precisely slits raw paper rolls into various widths based on customer orders, with no waste.
Roll Offset Printing
The printing department at Nami Naghsh utilizes a 2020 model roll offset press with intermittent capability and zero paper waste. It can simultaneously print 6 colors with rotary UV on adhesive-coated papers such as pearlescent PVC, transparent PVC, metalized, and glossy adhesive paper—delivering the highest quality, fastest speed, and most competitive prices to our valued clients.
Lithography
Our lithography department employs state-of-the-art polyester lithography and inline washing systems to separate colors based on design and specifications. This ensures the highest quality zinc plates and the best possible prepress output for our customers.
What is Roll Offset Printing?
Roll offset printing is one of the most advanced methods for mass production. It is especially used for high-volume jobs requiring excellent color accuracy. Printing is performed continuously on large rolls of paper or other substrates. Lithography transfers the image to the printing surface, allowing for precise and high-quality prints at scale. Files are separated into four CMYK colors, transferred through cylinders, and applied to the substrate with high accuracy, making this method ideal for detailed, high-resolution prints.
How Roll Offset Printing Works
As mentioned earlier, roll offset printing is an advanced method used for high-volume, premium-quality jobs. The artwork is separated into CMYK, transferred to aluminum plates via lithography, and coated with special polymers for exact color reproduction. Ink is indirectly transferred to a rubber blanket cylinder, which then applies the ink directly onto paper, film, or metal substrates. Rolls of paper or material are continuously fed into the machine for uninterrupted printing, making it perfect for large projects. Special techniques like hot foil and letterpress can be added for premium finishes and enhanced appeal.
Applications of Roll Offset Printing
- Roll Labels
- Magazines
- High-volume Books
- Newspapers
- POS Thermal Rolls
This method can print from one to four colors in sizes such as 52, 80, and 110 mm, or fully customized dimensions.
Roll Offset Printing Machines
Roll offset presses are divided into two categories:
- Newspaper presses designed for lightweight paper at high speed.
- Commercial presses designed for high-quality jobs like magazines and brochures. These presses are ideal for industries requiring fast, high-precision, large-scale printing.
After printing, finishing processes such as binding are crucial for producing professional and appealing final products like magazines and books.
Custom Roll Offset Printing: A Powerful Tool for Brand Personalization and Sales Growth
In today’s competitive market, brands seek personalization to stand out. Custom roll offset printing is one of the best options for producing branded, tailor-made labels and products. It allows businesses to print unique designs with detailed product information, enhancing brand presence and directly boosting sales.
