How to upload.

1. Start with the right file.

Upload PDF, JPG/JPEG, PNG or WebP, up to 50 MB per file. PDFs must contain one page per upload; a single page can contain multiple layers. For raster images, the live editor supports files below 40 megapixels.

Use your original artwork rather than a screenshot. Vector PDFs keep logos and lettering crisp. For photos and other pixel artwork, aim for 300 pixels per inch at the final print size: a 3 × 3 inch design should ideally be 900 × 900 pixels or larger. Increasing the file’s resolution setting alone won’t recover missing detail.

Embed linked images and fonts when exporting, or outline lettering in your design app while keeping an editable original. Check that your exported PDF opens correctly before uploading.

Transparent backgrounds

A PNG can have a genuinely transparent background—or a checkerboard baked into its pixels. If the checkerboard appears as part of your artwork, it can print. Use Remove background when needed, inspect the edges, and use Restore background to undo it. Keep any background that belongs to your design.

2. Understand the cut line and bleed.

The cut line is the boundary of the finished sticker or label. Background colors and images intended to reach the edge should extend beyond that boundary so trimming doesn’t leave an unwanted unprinted edge. That extra artwork is called bleed.

Keep text, logos, QR codes and other essential details comfortably inside the cut boundary. Don’t place them right on the edge. Follow the selected template and the editor’s guides; bleed and safe space are different from a decorative white border.

Standard shapes and die cuts

For circles, squares, rectangles, rounded rectangles and ovals, choose the shape and position your artwork inside it. For die cuts, review the detected outline and adjust the border as needed. Check that it follows the intended subject rather than the full rectangular image background.

Don’t draw a pink cut line into your printable artwork. The editor and production export create the cutting information from your approved shape. An existing cut path in your PDF is not automatically imported as the editor’s cut line. Remove visible guide strokes from the artwork, or ask us for help if you need a specific supplied path used.

3. Prepare a layered PDF with GLOSS.

You can supply your finishing areas in a real PDF layer named GLOSS. The editor imports that layer as an editable gloss map and hides it from the normal artwork preview.

1. Keep the printable design on its own artwork layer. Include the colors, images and lettering you want printed.
2. Create a separate layer named GLOSS. Use filled shapes over the areas you want finished. Solid shapes are easiest to inspect; their color does not determine the finishing strength. White shapes work too. Avoid an accidental full-page background in this layer unless you want the entire label coated.
3. Keep both layers on the same page and in the same positions. The gloss shapes should line up exactly with the corresponding printed details. Leave blank space wherever you do not want gloss.
4. Export one page while preserving PDF layers. Enable your design app’s PDF-layer or optional-content export setting. Don’t flatten or rasterize the layers. Check the exported PDF’s Layers panel: it should list GLOSS as a separate layer. A layer visible only in the original design file is not enough.
5. Upload and select a gloss or emboss finish. Look for the “GLOSS layer imported” message. Review the imported areas in the editor and proof, and correct anything that does not align.

The name is case-insensitive, so GLOSS and Gloss are recognized. Hidden GLOSS layers are read too. The importer uses the shapes’ opacity to identify coverage—not whether they are black, white or colored. Use opaque filled shapes for predictable selection.

A flattened PDF cannot provide a named gloss layer. Upload it as artwork and build the gloss map with the editor’s tools instead. Importing a GLOSS layer does not automatically select or charge for a specialty finish.

Example layer setup

• ARTWORK: your finished printable design.
• GLOSS: filled shapes over the logo or details receiving the selected finish.
• Guides: remove printable template marks and cut-line strokes before exporting.

The approved finishing map is included in the production file as the separate RDG_Gloss plate. Your uploaded GLOSS reference is not printed as colored artwork. Keep your original editable file in case changes are needed.

4. Choose where the finish goes.

Spot gloss adds shine to selected areas. Emboss and double emboss use that same selection for increasingly raised finishing. Choose the desired finish in your order details; a GLOSS layer tells the editor where to apply it, not which finish to order.

You can also create or refine a gloss map with the editor’s selection, brush and eraser tools. Inspect small lettering, narrow gaps and edges closely. Automatic selection and imported maps are starting points that still need your review.

The 3D view helps you see material, shine and raised texture. Its lighting and relief are a visualization, not a measured guarantee of physical coating height or an exact color match.

White areas and specialty materials

These orders do not currently include a white-ink underbase. On clear, holographic and metallic materials, white and transparent parts of your design reveal the material beneath. Light colors can also let the material show through. Check the material preview before approving; white vinyl provides a white backing.

5. Upload jar top and side labels separately.

Choose your jar first, then download its matching templates. Use the correct top and side dimensions for Miron 150 ml, Miron 100 ml, Miron 5ml, 4 oz Frosted CR or 2 oz Frosted CR. Don’t reuse a different jar’s template just because it looks similar.

Upload the top design into the TOP Label editor and the wrap design into the SIDE Label editor. Each upload may have its own GLOSS layer. A two-page PDF is not a substitute for these two separate files.

Review the circular top, the side label’s height, and the wrap seam in the 3D view. Keep essential text away from the seam and trimming edges. Approve both label surfaces. Jar Labels supplies labels only; Labeled Jars includes the jars with labels applied.

6. Review before approving.

• Confirm the product, material, quantity, finish and finished dimensions.
• Check spelling, legibility, QR codes and the quality of enlarged images.
• Make sure background removal hasn’t erased part of your design or left a baked-in checkerboard.
• Inspect the cut boundary, edge coverage and space around important details.
• Check that every gloss area aligns with the intended artwork.
• For jars, check and approve both the top and side labels.

Changing the design or order specifications requires a new proof approval. Screen previews help you check placement and finishing, but monitor colors and simulated materials are not exact print samples.
