Top 10 Questions for Machine Silk Screen Printer Interview

1. Describe the process of preparing a silk screen for printing.

• Degreasing the screen to remove any dirt or oils.
• Applying a photosensitive emulsion to the screen and exposing it to light through a positive film.
• Developing the emulsion to create a stencil of the desired image.
• Drying and hardening the stencil.

2. What factors affect the quality of a silk screen print?

Substrate

• Material (e.g., paper, fabric, plastic)
• Surface texture
• Absorption rate

Ink

• Viscosity
• Color
• Transparency

Screen Mesh

• Count (threads per inch)
• Material (e.g., nylon, polyester)
• Tension

Printing Technique

• Squeegee pressure
• Printing speed
• Number of passes

3. How do you troubleshoot common silk screen printing problems, such as ghosting, pinholes, and ink streaking?

• Ghosting: caused by ink bleeding through the stencil. Can be resolved by increasing exposure time, using a higher mesh count screen, or adjusting squeegee pressure.
• Pinholes: caused by small holes in the stencil. Can be resolved by inspecting the screen for damage or using a higher mesh count screen.
• Ink streaking: caused by ink flowing under the stencil. Can be resolved by adjusting squeegee pressure, increasing ink viscosity, or using a higher mesh count screen.

4. What is the difference between wet-on-wet and wet-on-dry printing?

• Wet-on-wet: printing multiple layers of ink while the previous layer is still wet. This allows for blending and creating special effects.
• Wet-on-dry: printing multiple layers of ink after the previous layer has dried. This provides better control over color and registration.

5. How do you maintain and store silk screens to ensure their longevity?

• Cleaning screens immediately after use with water or solvent.
• Storing screens in a cool, dry place away from direct sunlight.
• Inspecting screens regularly for damage and repairing any holes or tears.

6. What safety precautions should be taken when working with silk screen printing equipment and materials?

• Wearing appropriate safety gear (e.g., gloves, apron, respirator).
• Ensuring proper ventilation in the printing area.
• Storing chemicals and solvents safely and disposing of them properly.

7. How do you ensure accurate registration when printing multiple colors on a single item?

• Using registration marks on the screen and substrate.
• Inspecting the registration regularly throughout the printing process.
• Adjusting the printing press or screen position as needed.

8. What is the best way to mix and prepare ink for silk screen printing?

• Following the manufacturer’s instructions for mixing ratios and curing times.
• Using a scale to ensure accurate measurements.
• Thoroughly mixing the ink with a stir stick or spatula.

9. How do you handle special printing techniques, such as metallic inks or discharge printing?

In addition to the standard silk screen printing process, I have experience with specialized printing techniques such as metallic inks and discharge printing. For metallic inks, I ensure that the substrate is properly prepared and use a high-quality adhesive to prevent the ink from flaking. For discharge printing, I carefully control the printing temperature and time to achieve the desired effect without damaging the fabric.

10. What are the latest trends and innovations in silk screen printing?

I keep myself updated with the latest trends and innovations in silk screen printing. Some emerging trends include the use of digital printing techniques to create high-quality, full-color prints, and the development of new inks and materials that allow for printing on a wider range of substrates. I am eager to explore these new technologies and incorporate them into my work.
