How Atlantic Coated Paper Uses Our Color Viewer Light Table

At Qualitest, we work with manufacturing teams across the globe, and we will be direct: high-speed polymer extrusion coating leaves zero margin for visual guesswork. Within our broader Light Booth - Color Light Box equipment family, our specialized color tables are built specifically for industrial facilities where visual consistency is evaluated on every single production run.

Over at Atlantic Coated Papers, production crews in Whitby and Windsor convert significant volume every single day. Super-hot molten polymer bonds directly to wide rolls of base paper, aluminum foil, and plastic film at high line speeds. They supply critical barrier materials that consumer brands depend on daily:

• Food & Dairy Packaging: Multi-layer butter wrap structures that must block moisture and grease while displaying crisp, uniform brand graphics.
• Pharma & Medical Barriers: Multi-ply webs where even a micro-sized void in the barrier layer cannot be accepted.
• Specialty Industrial Sheets: Heavy-duty Barrier Board™, automotive masking papers, and compostable polymer laminates built to withstand demanding field conditions.

When converting thousands of square meters per shift, the inspection routine has to keep up with the machinery. As wide-web rolls come off the rewinder, quality operators slice full-width cross-cut sheets and move them straight to the Color Viewer Light Table QT-CC120-D station for immediate offline evaluation. Releasing an off-shade or streaky master roll creates serious operational headaches.

Optical Challenges: Metamerism, Opacity, and Ambient Lighting

From our experience with industrial converters, visual quality control on coated substrates presents distinct technical hurdles. Once a glossy polymer film bonds to porous paper fibers, surface reflection and light penetration change significantly. Standard compact viewing cabinets simply cannot accommodate wide production cuts.

Even if an automated in-line scanner records acceptable numbers, human evaluation remains essential for spotting subtle shade variations that instruments overlook. We see three core challenges across converting facilities:

• The Phenomenon of Metamerism: A printed package might look acceptable under standard factory lighting, but the moment it sits under cool white TL84 fluorescent tubes in a supermarket display cooler, the shade can shift noticeably.
• Subsurface Voids and Coating Streaks: Looking strictly at the top surface leaves blind spots. Inspectors need clear, diffused light shining from underneath the sheet to verify that the polymer layer is even and free of pinholes.
• Shift-to-Shift Lighting Inconsistency: Bright afternoon sunlight coming through facility windows creates an entirely different visual environment than the artificial lighting on a night shift.

Atlantic Coated Papers wanted to remove this uncertainty entirely. Their quality team selected the Color Viewer Light Table QT-CC120-D configuration to ensure every operator evaluated color and coating uniformity against identical criteria.

Strategic Capital Allocation in QC Infrastructure

Let us share our view on testing equipment procurement: for years, legacy brands have charged high markups for standard visual inspection stations. In our opinion, paying double the price for an aluminum frame fitted with standard fluorescent tubes does not represent smart capital allocation.

Within our Light Booth - Color Light Box catalog, we configure the QT-CC120-D to match exact production requirements—whether a facility needs a single D65 source, a dual D65/D50 setup, or a complete 3-light upper arrangement paired with a bottom light table. We believe testing equipment should be built solidly out of heavy-gauge materials, meet international testing criteria to the exact letter, and deliver a sensible return on investment.

When Atlantic Coated Papers evaluated their options, they focused on clear operational requirements:

• Full Regulatory Compliance: Strict conformity with ISO 3664:2009 standards.
• Dual-Direction Illumination: Overhead multi-source lighting (D65, D50, TL84) combined with a lower backlit table for translucency checks.
• Industrial Build Quality: A workstation sturdy enough to handle large-format production samples shift after shift.

Our Color Viewer Light Table QT-CC120-D provided the right answer: full optical compliance for global packaging audits, without legacy pricing premiums.

Workstation Design and Operational Workflow

We built the Color Viewer Light Table QT-CC120-D so quality personnel can evaluate large-format samples quickly and thoroughly, combining multiple inspection tasks into one integrated station.

1. Multi-Illuminant Metamerism Verification

Quality technicians can place a freshly cut production sheet against the 135 × 217 cm glare-free neutral grey vertical backboard alongside the approved master sample. With the 3-light upper configuration, switching between D65 Daylight (6500K), D50 Graphic Arts Proofing (5000K), and TL84 Store Lighting (4000K) takes a second, confirming whether inks and coated substrates maintain their intended shade under retail lights. (For facilities with simpler requirements, we also offer the QT-CC120-D in single-source D65 or dual-source D65/D50 upper arrangements.)

2. Transmitted Light for Coating and Barrier Verification

Placing wide-web samples flat on the 135 x 90 cm frosted worktable and turning on the transmitted lower light source projects uniform, diffused illumination up through the sheet using a 6-tube lower array (selectable in D65, D50, or TL84). Any uneven polymer distribution or pinhole imperfection becomes immediately noticeable.

3. Secure Storage for Master Color Standards

Master color swatches and retain samples lose their value if they get creased or dirty. Three heavy-duty steel drawers built directly into the base of the workstation keep approved color standards protected, flat, and organized right at the inspection area.

Operational and Commercial Results

In our view, adding the Qualitest QT-CC120-D to a busy manufacturing facility like Atlantic Coated Papers delivers practical, long-term benefits:

• Eliminated Cross-Shift Discrepancies: Standardized ISO 3664 lighting ensures that a sample inspected at midday receives the exact same evaluation as one checked in the middle of the night.
• Quicker Roll Sign-Offs: Combining an overhead hood and a lower backlit table allows technicians to inspect surface color and barrier consistency in a single stop.
• Reliable Customer Assurance: Pre-emptively verifying roll stock under retail lighting conditions protects customer brand equity and reduces the risk of quality claims.
• Disciplined Capital Spending: Atlantic Coated Papers met their quality assurance goals while keeping their capital budget focused on broader operational priorities.
