Introduction to Screen Printing

Screen printing, also known as silk screening, is a highly adaptable printing technique that involves transferring ink through a mesh screen onto a substrate. It is widely employed in various industries, including textiles, advertising, and manufacturing, due to its ability to deliver precise and vibrant designs on diverse materials such as textiles, plastics, metals, and glass.

The Significance of Chemicals in Screen Printing

Chemicals play a pivotal role in the screen printing process, ensuring optimal print quality, durability, and consistency. Screen printers use different chemicals at various stages to prepare, clean, and maintain screens, as well as to remove unwanted ink and residues. Let us explore some essential chemicals used in screen printing and their specific functions.

Ink Wash: Preserving Cleanliness and Print Consistency

Ink wash is a specialized cleaning solution used to remove ink from screens and tools. After printing, ink residue can accumulate on the screen, potentially affecting the quality of future prints. Ink wash effectively dissolves and eliminates ink, keeping the screen clean and primed for subsequent use. It is crucial to select an ink wash that is compatible with the type of ink used in the printing process for optimal results. Example of a good ink wash for plastisol inks is Victory Factory Ink Wash and for water based inks Franmar Aquawash.

Haze Remover: Eliminating Ghost Images and Ensuring Clarity

Haze remover plays a vital role in eliminating ghost images or haze that may appear on screens over time. It occurs when ink or emulsion residue remains on the screen after cleaning, leading to blurred or distorted prints. You can use Haze remover to effectively eradicates these remnants, restoring the screen's clarity and ensuring sharp and accurate prints. Use Victory Factory Haze Remover for best results.

Degreaser: Enhancing Adhesion and Preventing Ink Issues

Before applying the stencil to the screen, it is crucial to remove any oils, grease, or contaminants from the mesh. Degreasers are specially formulated chemicals designed to eliminate these substances, ensuring proper adhesion of the stencil and preventing ink from bleeding or smudging. Utilizing a suitable degreaser prepares the screen for optimal ink transfer and enhances print quality.

Emulsion Remover: Efficient Screen Reclamation and Reusability

Emulsion is a photosensitive material utilized in creating the stencil on the screen. Because over time, the emulsion may degrade or sustain damage, necessitating its removal for screen reclamation or reuse. Emulsion removers are chemical solutions that break down and dissolve the emulsion, facilitating easy removal and screen cleaning. Examples of a great quality emulsion removers are Victory Factory Reclaimer and Easiway Supra.

Spot Remover: Tackling Ink Mishaps and Maintaining Flawlessness

During the screen printing process, ink mishaps may occur, leading to undesired ink stains on substrates or garments. Spot removers are potent solvents designed to eliminate such ink stains effectively. By dissolving the ink, spot removers aid in the cleaning process, preventing stains from compromising the final product's quality. AlbaChem Spif 2 is a good example of high quality spot remover. Use Wet Ink Remover to remove uncured wet ink immediately after it happens. Another good product is Wet Ink Remover. Use it to remove wet ink from garments as soon as it happens.

Adhering to Proper Handling and Safety Measures

When working with chemicals in screen printing, it is imperative to follow proper handling procedures and safety measures. Some chemicals may pose hazards if mishandled. Always wear protective gloves, goggles, and clothing to minimize exposure. Additionally, ensure proper ventilation in the workspace to avoid inhaling fumes. Adhere to the manufacturer's instructions and dispose of chemicals safely in accordance with local regulations.


The use of chemicals in screen printing plays a fundamental role in achieving high-quality and long-lasting prints. Ink wash, haze remover, degreaser, emulsion remover, and spot remover are essential chemicals employed at various stages of the screen printing process. By understanding their functions and utilizing them appropriately, printers can ensure optimal print quality, durability, and overall success in their screen printing endeavors.


1. Can I reuse emulsion after applying an emulsion remover?

No, once the emulsion has been removed using an emulsion remover, it cannot be reused. It is necessary to apply a fresh layer of emulsion for subsequent printing jobs.

2. Is it necessary to use a specific degreaser for screen printing?

Yes, it is important to use a degreaser specifically formulated for screen printing. Regular household cleaners may not effectively remove all contaminants, potentially leading to print quality issues.

3. Can spot removers be used on all types of fabrics?

Spot removers should be used with caution on fabrics. Before applying spot remover, test it on a small, inconspicuous area first to ensure that the spot remover does not cause any damage or discoloration.

4. Are there eco-friendly alternatives for screen printing chemicals?

Certainly, there are eco-friendly options available for certain screen printing chemicals. Look for products labeled as environmentally friendly or explore water-based alternatives.

5. How often should I clean the screen with ink wash?

It is recommended to clean the screen with ink wash immediately after each printing session to prevent ink buildup and maintain optimal print quality.
