In the flexographic printing industry, having the right photopolymer plate processor is crucial for meeting diverse printing needs. Different types of flexo platemaking equipment offer unique advantages depending on a converter’s specific requirements. But which type of flexo platemaking is right for you?

To achieve top-notch quality and efficiency, understanding the differences between the four main types of photopolymer processors – water-wash, thermal, solvent, and liquid – is essential.

Water-wash flexo platemaking

For narrow web printers seeking an eco-friendly flexo platemaking solution, water-wash processors are an excellent choice. These processors are designed to be solvent-free, reducing VOC emissions and environmental impact. Water-wash photopolymer processors use tap water for the washout process, allowing for the recycling and reuse of the water. This approach not only benefits the environment but also enhances productivity with shorter drying times.

Key Benefits:

• Environmentally friendly with reduced VOC emissions
• Shorter drying times for improved efficiency
• Suitable for eco-conscious printing operations

For example, Toyobo, a pioneer in water-wash photopolymer plates, offers solutions that:

• Utilize the latest Computer-To-Plate (CTP) technology
• Deliver clear reproduction of screen dots and letters
• Provide consistent plate quality and durability

Thermal flexo platemaking

Thermal platemaking is highly popular in the flexographic industry due to its simplicity and quick turnaround times. This method eliminates the need for water or solvents, making it a low-maintenance option. Thermal processors improve print quality with better edge definition and consistency across multiple print runs.

Key Benefits:

• No need for solvents or water, reducing maintenance
• Enhanced print quality and consistency
• Faster processing with no drying required

For example, XSYS’s nyloflex Xpress Thermal Processing System:

• Offers precise control of heat distribution
• Promotes energy efficiency and conservation
• Ensures fast turnaround times

Solvent flexo platemaking

Solvent platemaking has been a staple in the flexographic industry for many years. Although it involves chemical solvents, recent advancements have introduced more environmentally friendly and less hazardous options. Solvent processors are known for their productivity and effectiveness in various applications.

Key Benefits:

• Long-standing, reliable technology
• High productivity with effective solvent usage
• Recent developments in environmentally friendly solvents

For example, Vianord solvent processors:

• Provide digital layer separations and improved washout speeds
• Offer precise temperature control and touchscreen operations

Liquid flexo platemaking

Liquid plate making is ideal for corrugated packaging applications such as pizza boxes and grocery packaging. This method involves using an exposure unit, UV lights, and a washout system to create high-quality plates. Liquid photopolymer resins offer a cost-effective and efficient solution for various printing needs.

Key Benefits:

• Economical and efficient for corrugated printing
• Delivers high-quality print results with optimum elasticity
• Suitable for a wide range of applications

Meanwhile, Anderson & Vreeland’s AVantage Liquid Photopolymers:

• Reduce environmental impact and control costs
• Provide excellent elasticity, hardness, and ink transfer
• Available in formulations tailored to specific markets
