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.

Silver Digistar Silver Eraser Pen PX

Silver Digistar Silver Eraser Pen PX

A cover coat type eraser pen (for film CTP and analog plates) that you simply paint over the area you want to erase on the Silver Master plate.

The "Silver Deletion Pen PX" is a cover coat type eraser pen that simply requires you to paint over the area you want to erase on the silver master plate. Traditional eraser pens for silver masters worked by dissolving the image area, but the "Silver Deletion Pen PX" adopts a cover coat method that hydrophilizes the image area to form a non-adhesive film, preventing ink from adhering. If you apply it more than three times to the areas you want to erase on film CTP masters and analog masters, the erasure will be complete, and even if the image area is visible, ink will not adhere. 【Features】 ■ Cover coat type that can erase without removing the image ■ As it is a cover coat type, it forms a non-adhesive film just by painting over the area to be corrected (erased) ■ It only requires a light application, so it does not damage the silver master *For more details, please refer to the PDF document or feel free to contact us.

Executive Brainstorming / President's Secret Base - Leader's Salon

"CEO's Wall-Bouncing" - A special salon for the president to organize their thoughts. Shall we draw the map of the future from here?

"What do you think of this idea, objectively?" "Should I choose path A or B...?" "I can't tell my employees, but I'm actually struggling with this..." Business owners are faced with various decision-making pressures. However, there is no one to help them organize their thoughts and confirm their ideas from an objective perspective. The CEO's secret base is a salon for one-on-one sessions that alleviates the "loneliness of management" with complete confidentiality. We leverage our expertise in strategy, organization, and branding to listen to the words of business owners, pose questions back, and offer new perspectives. Instead of "providing answers," we draw out the best "answers" from within the CEO and refine them together. This will be the first step to accelerating your future. The CEO's secret base is an "intellectual safety space" designed to enhance the power of business owners to take on challenges. Would you like to organize your thoughts and refine your decision-making through a CEO session? ○ Turn anxiety into confidence! ○ Transform vague ideas into concrete strategies! ○ Organize and tidy up the confusion in your mind!
