Chromaline CP2 screen printing emulsion

The product offers wide exposure latitude, allowing relatively consistent stencil production even when minor variations occur in exposure conditions. CP2 is also suitable for applications requiring precise reproduction of fine details, thin lines, and sharp images.

One of its most notable advantages is its excellent screen reclaimability, making it easier to remove the emulsion after printing and prepare screens for reuse.

This makes CP2 particularly suitable for screen-printing operations that regularly clean, reclaim, and reuse their screens for different printing jobs rather than using each screen only once.

Key Features

1. Wide Exposure Latitude

Exposure time is a critical factor in the screen-making process.

Insufficient exposure may prevent the emulsion from hardening completely. Conversely, excessive exposure can make it difficult to properly wash out fine image details, small lettering, and thin lines.

CP2 provides wide exposure latitude, helping maintain relatively consistent stencil quality even when minor variations occur in working conditions or exposure equipment.

This characteristic makes the emulsion convenient for practical production environments where maintaining exactly identical exposure conditions for every screen can be challenging.

2. Sharp and Precise Image Reproduction

CP2 is suitable for applications requiring high-resolution image reproduction.

The emulsion helps produce sharp, well-defined stencils for designs containing small lettering, fine lines, logos, and intricate graphics.

It is particularly useful for printing applications that require accurate and consistent reproduction of detailed designs over repeated print runs.

3. Excellent Screen Reclaimability

One of the major advantages of CP2 is its excellent screen reclaimability.

After completing a printing job, operators can remove the existing emulsion, clean the screen mesh, and prepare the screen for a new design.

Emulsions that are difficult to remove can increase the time and labor required for screen reclaiming and may also increase the risk of mesh damage.

CP2 is designed to make emulsion removal and screen cleaning more convenient, helping improve operational efficiency for printing facilities that frequently reuse their screens.

4. Balanced Stencil Durability and Reclaimability

Screen printing emulsions must satisfy two important requirements: maintaining sufficient stencil durability during printing while remaining removable after the printing job is completed.

CP2 is developed to balance these characteristics, helping maintain a stable stencil throughout the printing process while allowing relatively easy emulsion removal during screen reclaiming.

This makes the product suitable for production environments involving repeated print runs, frequent artwork changes, and regular screen reuse.

5. Solids Content – 21.3%

CP2 has a solids content of 21.3%.

Solids content refers to the proportion of solid components remaining on the screen mesh after the liquid emulsion has been coated and dried, forming the stencil film.

By appropriately combining solids content, viscosity, and the number of coating passes, operators can achieve the desired stencil characteristics and thickness for specific printing applications.

6. Medium Viscosity – Consistent Coating Performance

CP2 features medium viscosity.

As the emulsion is neither excessively thin nor overly viscous, it is convenient to handle during conventional screen coating operations.

When appropriate coating techniques are used, CP2 helps form a relatively uniform emulsion layer across the screen mesh, contributing to consistent stencil quality.

7. Violet or Blue Color Options

CP2 is available in two color options: Violet or Blue.

The colored emulsion helps operators inspect coating coverage, identify image areas, and check stencil conditions during the exposure and washout processes.

8. Freeze/Thaw Stability

CP2 is formulated with freeze/thaw stability, providing improved resistance to conditions in which the product may be exposed to freezing temperatures and subsequently thawed during transportation or storage.

This characteristic is particularly relevant during winter transportation or shipping to regions with cold climates, where emulsions may be exposed to low temperatures.

The freeze/thaw stability of CP2 helps maintain product quality under such temperature variations.

Note: Photosensitive emulsions are sensitive to temperature and light. Therefore, the product should always be stored according to the manufacturer's recommended storage conditions.
