What Is Chromaline ProCap® 15 Capillary Film?
Capillary film is pre-sensitized photopolymer emulsion supplied as a dry sheet. Instead of coating your screen with liquid emulsion (and waiting hours for multiple coats to dry while fighting orange peel), you apply the film to a wet mesh, squeegee it down, and the capillary action of the wet threads draws the film into the mesh. The result: a perfectly uniform stencil thickness in minutes instead of hours.
Chromaline ProCap® 15 Capillary Film is the thinnest ProCap in Chromaline’s diazo capillary film line — engineered for screen printers chasing the sharpest possible halftone and line detail. The 15-micron stencil thickness is specifically calibrated for high-resolution halftone printing — different thicknesses in the ProCap and Chromaline capillary film lineup are engineered for different LPI halftone ranges and ink deposit requirements.
Stencil thickness directly controls ink deposit. A 15-micron stencil deposits a specific volume of ink optimized for 75+ LPI halftone work on 390+ thread count mesh. Go thinner and your halftones get sharper but coverage drops; go thicker and coverage improves but fine detail blurs. The ProCap lineup exists because no single thickness handles every screen printing application — Chromaline ProCap® 15 Capillary Film is the right answer for high-resolution halftone printing.
Where Chromaline ProCap® 15 Capillary Film Fits in the Chromaline Capillary Film Lineup
Chromaline makes capillary films across a wide thickness range — from 15 microns for ultra-fine detail up to 700 microns for extreme high-density 3D effects. Pick the thickness that matches your design’s LPI/halftone requirements and your ink type. Click any thickness to view that product:

What Chromaline ProCap® 15 Capillary Film Is Used For
Chromaline ProCap® 15 Capillary Film’s 15-micron thickness is calibrated for these primary applications. If your work matches any of the below, this is the right capillary film:
Watch: How to Apply Capillary Film
Two video demonstrations from Chromaline showing the capillary film application process — start with the general technique overview, then watch the ProCap-specific walkthrough. The application method is the same for Chromaline ProCap® 15 Capillary Film: degrease, wet mesh, lay film, squeegee, dry, expose. Watch before your first attempt to see what proper film-to-mesh contact looks like in real time.
General capillary film application technique — the roll-down method that works for all Chromaline capillary films including Chromaline ProCap® 15 Capillary Film.
ProCap-specific application walkthrough — same technique applies to Quick Film and Super PHAT, with the bonding emulsion step optional or required depending on the film.
Step-by-Step: Applying Chromaline ProCap® 15 Capillary Film to Your Screen
The standard roll-down method below works for Chromaline ProCap® 15 Capillary Film. Larger production shops sometimes use spray-gun methods for lighter water application, but the roll-down approach is the proven workflow. Total active time: 10-15 minutes plus drying.
Start with a properly degreased, fully dry screen using mesh in the 390+ thread count sweet spot for Chromaline ProCap® 15 Capillary Film. Yellow mesh is strongly preferred for any fine-detail capillary film work — it absorbs scattered UV during exposure for cleaner edges.
Open the ProCap film only under yellow safelight or low-wattage tungsten bulbs. AVOID daylight, fluorescent, quartz/halogen, and cool-white LED — these will pre-expose the film. Cut about 1″ larger than your image area.
Spray or wipe the mesh side with clean filtered water until uniformly wet — not dripping, not dry. The capillary action of the wet threads is what draws the film into the mesh.
With the film side DOWN (toward the wet mesh) and the Mylar carrier UP, lay the film flat. Smooth any wrinkles by hand before squeegeeing — once water wets the film, you can’t reposition it.
Use a soft squeegee or window-squeegee. Light pressure, working from center outward to push water and air bubbles to the edges. Multiple light passes beat one heavy pass.
For small bubbles in the image area, wet your finger and touch the bubble. Capillary action will pull the film tight to the mesh, eliminating the bubble.
Lay flat to dry. Diazo films like Chromaline ProCap® 15 Capillary Film typically dry in 2-4 hours depending on environmental conditions. Drying position doesn’t matter.
For maximum durability and edge definition, coat the print side with a Chromaline diazo or dual-cure emulsion (Hydro-X, CP-Tex, etc.) and dry again. This step is optional for short runs but adds significant longevity for production-volume work.
Diazo chemistry — moderate exposure time. Use metal halide or LED UV exposure (not fluorescent). Run an exposure step test on a small area first to dial in your specific shop’s optimal time. Wash out gently with low-pressure water, inspect for clean edges and full image.
Unlike Super PHAT (which REQUIRES a bonding emulsion), ProCap diazo films can be used standalone OR laminated with a Chromaline textile emulsion. For runs over a few hundred impressions, lamination significantly extends stencil durability. For short-run jobs, standalone application works fine.
Pro Tips for Chromaline ProCap® 15 Capillary Film
Distilled from Chromaline’s technical documentation, shop experience, and customer feedback. Save yourself the trial-and-error:
For Chromaline ProCap® 15 Capillary Film, target 390+ thread count. Going too fine restricts ink flow; going too coarse loses the detail capability Chromaline ProCap® 15 Capillary Film provides. The mesh + capillary film combination is the system — neither works in isolation.
Yellow mesh absorbs scattered UV during exposure, preventing light bounce inside the threads. For halftone or fine-detail work, yellow mesh is worth the modest price premium — it saves screens from re-burning when fine edges blur on white mesh.
ProCap is diazo chemistry — moderate exposure time. If you’re switching from Quick Film (photopolymer) or other photopolymer films, expect to roughly DOUBLE your exposure time. Run a step test on the first screen of any new ProCap variant to dial in your shop’s optimal exposure.
ProCap can be used standalone, but for production runs over a few hundred impressions, laminating with a Chromaline textile emulsion (like Hydro-X Blue or CP-Tex) significantly extends stencil life. It takes 10 minutes more — but doubles or triples stencil durability.
Fluorescent exposure units don’t have enough UV intensity to fully cure capillary film, especially thicker variants like ProCap 38 and 50. If you have a fluorescent unit and you’re seeing soft edges or wash-out problems, the unit is the issue — not the film.
Every shop has slightly different exposure requirements based on lamp age, distance, mesh color, and ambient humidity. Burn a 21-step Stouffer wedge on a small test screen before committing your full daily screen run to a new ProCap variant. The 10 minutes invested saves hours of reclaim work.
Exposure Unit Requirements
All Chromaline capillary films need proper UV exposure to cure correctly. Underexposure causes the image area to wash out during development — leaving you with no usable stencil. Here’s what works:
- Metal Halide units (3-7KW typical) — the industry-standard exposure source
- LED UV exposure units — modern shop standard, fast cure times
- High-power mercury vapor lamps
- Used with yellow mesh for best edge definition on detail work
- Fluorescent / BLB exposure units — usually too weak for thick films
- Sunlight exposure — uneven, unpredictable
- Standard household UV lamps — not enough power
- Reptile bulbs & hobbyist UV — won’t fully cure
Capillary Film vs Liquid Emulsion — When to Use Which
Both have their place. For high-detail, halftone, and consistency-critical work, capillary film like Chromaline ProCap® 15 Capillary Film produces better results. For everyday standard plastisol work in mid-LPI range, liquid emulsion remains the cost-effective choice. Here’s the honest comparison:
| Factor | ★ Chromaline ProCap® 15 Capillary Film (Capillary Film) | Liquid Emulsion |
|---|---|---|
| Thickness Consistency | ★ Uniform across entire screen (factory-cast) | Variable — depends on operator coating technique |
| Edge Definition | ★ Sharper edges, especially at high LPI | Good with skill, but coating variability shows |
| Setup Time Per Screen | ★ Faster — one application, single dry | Multiple coats + dry between each |
| Cost Per Screen | Higher per-screen for consumable cost | ★ Lower per-screen consumable cost |
| Learning Curve | ★ Easier — uniform results regardless of operator | Coating skill required for consistent results |
| Best Application | ★ High-detail, halftones, consistency-critical | Standard plastisol work, larger format screens |
Stock Chromaline Hydro-X liquid emulsion for everyday standard plastisol work AND Chromaline ProCap® 15 Capillary Film for high-detail / halftone / fine-line screens. Each tool for its right job — forcing one to do the other’s work costs you time and quality.
