Notice of Price Revision for Emulsion Products

Increased the viscosity of the ink roller color change cleaning agent "Color Wash" and developed "Wash Up" as a sister product.

"Wash Up" has a higher viscosity than color wash, which increases the retention time on the ink roller during color changes, enhancing the effect of removing hydrophilic substances such as paper dust and dampening liquid components other than ink. It has a higher water content compared to other emulsion-type cleaners, making it more effective in removing paper dust. This product is particularly recommended for proofing machines that frequently undergo color changes. It has minimal impact on the ink roller, helping to reduce its lifespan deterioration. 【Features】 - Designed as a product not subject to the PRTR Law or Organic Solvent Law - Being an emulsion type, it simultaneously removes ink and paper dust or hydrophilic components from the ink roller - Minimal impact on the ink roller, helping to reduce lifespan deterioration - Increased cleaning power allows for reduced usage, contributing to cost savings - Improved emulsification stability to prevent separation and viscosity increase *For more details, please refer to the PDF document or feel free to contact us.

To improve the ink solubility, the formulation ratio of the solvent components is increased, and the viscosity is kept low to ensure better doctor blade performance.

"Roller Fresh" has been designed to improve ink solubility by increasing the proportion of solvent components and keeping viscosity low, resulting in better doctor blade performance. During the color change cleaning of ink rollers, hydrophilic substances such as paper dust and dampening solution components, other than ink, remain on the roller, preventing ink adhesion. To wash these hydrophilic substances along with the ink, we have developed "Color Wash," an emulsion-type cleaning agent, and now we have created "Roller Fresh," which enhances ink cleaning power. 【Features】 ■ Simultaneously cleans and removes ink, paper dust, and hydrophilic substances from the ink roller ■ Minimal impact on the rubber components of the ink roller, reducing lifespan deterioration ■ Reduced usage due to improved ink cleaning power, contributing to cost savings ■ Enhanced emulsion stability by increasing the proportion of solvent components and keeping viscosity low *For more details, please refer to the PDF document or feel free to contact us.
