[Sold Out] Astro Choking Check Pen

[Sold Out] Astro Choking Check Pen

[Discontinued] Paper Drying Defect Check Pen 'Astro Chalking Check Pen'

The "Astro Chalking Check Pen" is a pen that allows you to confirm the risk of chalking due to the acidity of the paper. When printed on highly acidic paper, chalking can occur, where only the pigment components of the ink easily come off like powder when rubbing the dried print. Since printing can still be done on highly acidic paper, discovering chalking in the later stages can lead to significant losses due to reprinting. 【Features】 - You can easily check the risk of chalking by lightly applying the solution to the paper, helping to avoid troubles. - Its pen shape makes it portable, allowing for easy checks on the work site. - The degree of risk for chalking can be confirmed by differences in color development. *For more details, please refer to the PDF document or feel free to contact us.

Astro high-quality and medium-quality paper check pen

Astro high-quality and medium-quality paper check pen

A detection pen that can easily distinguish between high-quality paper and medium-quality paper based on the color when written with a pen.

The "Astro Quality and Medium Quality Paper Check Pen" is a product that allows for easy differentiation between quality paper and medium quality paper based on the color when applied with the pen. Medium quality paper contains components that react to ultraviolet light, causing it to fade or discolor when exposed to sunlight. To protect important books and documents from fading or discoloration, Nikkengaku has developed a pen that allows for easy identification of paper types. 【Features】 ■ Differentiation can be performed simply by lightly applying the reagent to the paper. ■ In the case of quality paper, there is no color change and it remains colorless, while medium quality paper changes to a reddish-purple color. ■ The more ground pulp contained in the paper, the darker the color change will be, so the intensity of the color serves as a guideline. *For more details, please refer to the PDF document or feel free to contact us.

Astro Neutral Paper Check Pen

Astro Neutral Paper Check Pen

A check pen that can easily distinguish between neutral paper and acidic paper.

The "Astro Neutral Paper Check Pen" is a product that allows for easy differentiation between neutral and acidic paper. Traditionally, concerns have been raised about the preservation issues of commonly used acidic paper (such as yellowing and damage due to oxidation), leading to a significant increase in the use of neutral paper. In places where books are managed, it is used to identify important documents made from acidic paper so they can be recreated using neutral paper, or to reconsider the management methods of books. In the printing industry, it is used to prevent printing troubles by easily distinguishing between acidic and neutral paper, which have different printing suitability. 【Features】 ■ Allows for differentiation of neutral paper without the use of pH meters ■ Lightly apply the reagent to the paper you want to identify, and differentiation can be made based on the color *For more details, please refer to the PDF document or feel free to contact us.
