By following these tips and tricks, you can unlock the full potential of Bitmap Viewer Esko and take your image editing skills to the next level.
Unlike standard image editors that blur pixels when zooming in, Esko Bitmap Viewer displays a Grid View. This overlays a grid on the image, allowing the operator to count individual pixels. This is critical for:
Always run Bitmap Viewer analysis after any last-minute trapping or barcode replacement. It is the final quality gate before plate exposure. Many press-side defects (bridging, broken type) are invisible in PDF proofs but glaringly obvious in Bitmap Viewer.
Summary: In the Esko ecosystem, the Bitmap Viewer is not just a "viewer" — it is a prepress microscope that ensures the digital file will print exactly as intended, dot for dot.
The Esko Bitmap Viewer is a critical quality control tool designed to verify RIPped data (the digital version of what will actually be printed) before it ever reaches a plate or press. By allowing users to inspect the final output at the pixel level, it serves as the last line of defense against costly printing errors. Key Features for Precision Control

Let’s look at real-world problems solved by the Esko Bitmap Viewer.
Problem: "The solid areas look OK, but the fine text on the flexible package is unreadable." Bitmap Viewer Diagnosis: Zoom into the text area. You are likely using a conventional dot screen. At the edges of the text, the dots are aliased. Solution: Switch to Hybrid screening (Samba) which keeps text as a solid rim but screens the interior.
Problem: "There’s a weird repeating pattern in the gradient of our corrugated box." Bitmap Viewer Diagnosis: Zoom into the gradient. You might see "jumping" dots (the transition from one dot size to the next is visible as a line). Solution: Adjust the screening curve or increase the resolution of the RIP output.
Problem: "My plates often show pinholes in the white separation." Bitmap Viewer Diagnosis: View the white separation bitmap. In the dark areas (where white is turned off), you might see "ghost" dots. Solution: Adjust the threshold in the RIP to ensure that anything below 0.5% is clipped to zero.
| Problem | Likely Cause | Solution | |---------|--------------|----------| | Can’t open file | Not a valid bitmap or unsupported format | Convert to uncompressed TIFF | | Slow zoom | Very large file (>500 MB) | Use 8-bit preview or crop | | No separation view | File is RGB or grayscale | Convert to CMYK in Photoshop first | | Measurements wrong | Unit mismatch (px vs. mm) | Set correct DPI in viewer | | Can’t see dot shape | Antialiasing enabled | Turn off “smooth images” |
The hallmark of a professional bitmap viewer is speed. Esko’s implementation uses optimized memory management. You can instantaneously zoom from a full press sheet view down to a 0.1mm halftone dot without waiting for re-rendering. This is known as "Resolution Independent Zoom."
Consider general-purpose bitmap viewers and prepress tools if you need broader file-format support or lower cost; however, Esko’s solution is tailored for packaging and print production workflows and often integrates tightly with Esko RIPs and automation platforms.
Assume you are a prepress operator using Esko ArtPro+ (the modern replacement for ArtPro and PackEdge for many workflows). You have a flexo file ready for screening.
Step 1: Rasterize the File
Before you can view a bitmap, the file must be rasterized. In ArtPro+, you go to Process > Create Bitmap. Here you select your screening (Samba, Pearls, default conventional), line screen (e.g., 150 lpi), and resolution (e.g., 2400 dpi). You output to a temporary TIFF or directly to the Bitmap Viewer.
Step 2: Launch the Bitmap Viewer
After rasterization, click the Bitmap Viewer icon on the toolbar or select View > Bitmap View. The application will load the raster memory.
Step 3: Navigate
Step 4: Select Screening Separations In the "Layers" or "Separations" panel of the viewer, toggle on "Cyan" only. Examine the dot structure. Note the shape and angle. Now toggle on "Magenta" only. Note its angle. Finally, toggle both on simultaneously. Look for a consistent, uniform rosette pattern. If you see dark clumps or long wavy lines, you have a moiré risk.
Step 5: Measure Critical Areas Navigate to a highlight area (like a sky or a smooth gradient). Use the "Info" tool to click on a dot. Ensure that the smallest dot present is above your press's minimum threshold (e.g., if your provider says 2% dots hold, ensure you don't see any 1% dots). Navigate to a shadow area (near 90%). Ensure the dots aren't touching too much.
Step 6: Compare and Save
Use the Snapshot feature to save a view (e.g., "3% dot in Cyan.png") for your quality report. If using Automation Engine, you can export a Bitmap Viewer report automatically as part of a Proof of Concept (PoC).
