What a proof can confirm, and what it cannot
Most custom acrylic projects start with a digital production proof. It is useful for checking dimensions, artwork placement, cut shape, hole position and hardware direction. It is not a reliable way to judge the exact printed color, acrylic edge finish, surface gloss or the feel of the attachment.
A physical sample gives you more information, but it may add setup cost and lead time. For a repeat order using a familiar construction, a detailed digital proof may be enough. For a new licensed character, a color-sensitive design, a special finish or a large order, a physical sample can be worth the extra step. Ask whether the sample uses the same print method, material thickness and hardware planned for bulk production.
Start with the final size and thickness
Confirm how the supplier measures the charm. A quoted 60 mm may mean the longest acrylic dimension, excluding the jump ring and clasp. Do not assume the hardware is included. Put the finished acrylic width and height on the proof, especially for an irregular shape.
Thickness affects weight, edge appearance and perceived sturdiness. Available options vary by supplier and product format, so the purchase order should name the agreed thickness rather than saying "standard acrylic." If a collection includes several sizes, check whether all SKUs use the same thickness.
- Finished acrylic width and height, excluding hardware
- Acrylic thickness and material type
- Single-piece or multi-piece construction
- Front-only, double-sided or different artwork on each side
Check the cut line at actual size
The cut line controls the silhouette and the clear border around the artwork. A border that looks modest on a large monitor can feel wide on a 40 mm charm. Review the proof at 100% size or print it on paper before approval.
Look closely at sharp corners, narrow gaps, hair strands, tails and small accessories. Some artwork needs a simpler outer contour so the acrylic can be cut cleanly and remain strong. If the supplier adjusts the cut path, compare the revised shape with the character outline instead of approving it from a thumbnail.
Ask whether the cut line shown is the actual production path and whether any printed area extends into the trimming allowance. Keep the approved PDF or image with the purchase order so everyone works from one version.
Inspect print layers, white ink and transparency
Transparent acrylic makes white ink important. On many printed acrylic charms, a white layer sits behind the color artwork so the image does not look washed out. Areas without white ink may remain transparent or semi-transparent, depending on the file and print process.
Tell the supplier which areas should be opaque, translucent or fully clear. Do not leave this to interpretation if the design includes windows, glasses, effects, pale skin tones or white clothing. For double-sided pieces, confirm whether both sides show the same image or separate artwork. Check that text reads correctly from the intended side.
| Proof item | Question to settle before approval |
|---|---|
| Color artwork | Is the correct final file placed at the intended scale and position? |
| White ink | Which areas are backed with white, and which areas stay transparent? |
| Front and back | Is the artwork orientation correct on both sides, especially for text? |
| Bleed | Does the print extend far enough to avoid an unintended unprinted edge? |
| Small details | Are thin lines and tiny text suitable for the supplier's print process? |
Do not approve color from a phone screen alone
Screen previews are affected by display settings, file color mode and the white ink beneath the print. A supplier can follow the supplied file and still produce a result that looks different from a backlit screen. If a brand color matters, share a Pantone reference or a physical color target and ask how the supplier handles color matching for that print method.
For a physical sample, view the charm in ordinary daylight as well as indoor light. Compare skin tones, pale colors, dark gradients and neighboring colors that need clear separation. Record any accepted variation before bulk production. A photo sent through a chat app can catch an obvious mistake, but it is not a controlled color standard.
Verify the hole, jump ring and clasp
The attachment point is part of the design. A hole too close to the edge can leave little material around it. A hole too far inside can cover artwork or make the charm hang at an odd angle. Confirm the hole diameter, its distance from the edge and the direction the finished charm should face when hanging.
Name the hardware rather than writing "keychain accessory." Lobster clasps, ball chains, phone straps, split rings and decorative clasps have different sizes and uses. Confirm metal color, connector rings and any decorative part. If a clasp shape or plated color is commercially important, ask for a clear close-up photo or a physical hardware sample.
- Hole position and diameter
- Jump ring quantity, size and metal color
- Clasp or chain type and finish
- Hanging direction when the hardware is assembled
- Protective film removal instructions, if film remains on delivery
Confirm surface finish and protective film
Acrylic pieces may arrive with protective film on one or both faces. Buyers sometimes mistake the film's haze or scratches for damage to the acrylic. Ask whether film is included, which side it covers and whether the factory removes it before packing.
If the product uses epoxy, holographic film, glitter, a textured surface or another special finish, approve its coverage and orientation. These effects can change how small details look. A digital mockup shows placement; a physical sample is the better reference for gloss, sparkle and surface feel.
Review packaging as part of the sample
Packaging affects the delivered condition of acrylic products. Individual bags help prevent pieces and metal hardware from rubbing together. A backing card can improve retail presentation, but its hole position, card size and barcode still need approval.
Ask for one assembled packing example before the order is fully packed. Check whether the clasp sits neatly, whether the charm faces forward, whether the bag seal covers printed information and whether the barcode can be scanned without opening the pack.
- Individual bag type and size
- Backing card artwork, thickness and hole position
- Barcode, SKU and country-of-origin text
- Quantity per inner pack and export carton
- Protection against surface rubbing during transit
Put approval comments in one document
Scattered comments in email and chat are difficult to control once several SKUs are in production. Use one approval sheet or marked PDF. Give each design a SKU, version number and date. Mark every item as approved, revised or still open.
When a revision arrives, check the whole proof again. A moved hole can affect the cut line. A changed cut line can alter the clear border. A corrected back print can introduce mirrored text. Do not review only the last comment.
Questions to ask before paying the bulk deposit
- Will bulk production use the exact file and construction shown in this proof?
- Is the white ink layer shown in the approval file?
- Does the quoted size exclude all hardware?
- What color-matching reference will production use?
- Is protective film left on the finished pieces?
- Can I approve one fully assembled packing example?
- What happens if the physical sample needs another revision?
- Will I receive pre-shipment photos covering print, edges, hardware and cartons?
