The design lives in two states.
Viewed from the side, a closed deck can show a continuous band of gold, silver, colour or another decorative treatment. In play, each card must release and the edge becomes a small accent around individual faces and backs. Decide which state matters most. A collector pack may prioritise the closed presentation; a working tarot deck may place more weight on clean separation and repeated handling.
Show references for colour and character, but do not treat a photograph as a process specification. Reflectivity, hue, coverage and edge texture change with light, material and method. Ask what edge process is proposed and whether it is suitable for the chosen card construction. The surface-finishing overview helps distinguish visual intentions from the technical route needed to achieve them.
Clean cutting prepares the visible edge.
Edge colour makes the cut surface part of the design. Stock layers, core colour, dark face coverage and cutting condition can influence what appears beneath or beside the treatment. A pale nick that would pass unnoticed on an ordinary deck may stand out against a dark metallic band. Include representative solid areas and fine borders in the sample set.
The finished corner also interrupts the edge. Confirm the card dimensions and radius before the effect and box are approved. A very dark face running to the edge may create a different visual transition from a white margin. The card border guidance can help keep normal cutting movement separate from expectations about a perfectly uniform printed frame.
Cards need to open and separate.
Inspect how the production-relevant deck is first opened. Some edge treatments and processes may require the cards to be separated or conditioned as instructed. Watch for transfer onto faces, rough patches, cards that remain joined, or an edge that cracks excessively when flexed. Record the sample age and any preparation rather than comparing a fresh sample with a long-handled reference.
Use the deck as intended after initial separation. Shuffle, cut and return it to the box. Wear at high-contact points may be expected, but the acceptable pattern belongs to the product brief. Do not promise permanent colour or zero transfer. The handling record provides a way to state actions and observations without turning limited use into an unsupported lifespan claim.
Face finishes and edge finishes must coexist.
A face coating, laminate or texture can affect how edges are cut, stacked and treated. Foil or raised decoration near the face edge may introduce another vulnerable feature. Bring all proposed operations into one feasibility discussion. Edge gilding should not be added to an already approved deck specification as if it were only a colour change.
Terminology varies. Metallic foil on a card face, hot foil on a box and a metallic edge treatment are different operations even when the same gold reference appears in the design. The digital decoration comparison covers face-applied effects; keep its masks and approval route separate from the treatment applied to the trimmed stack.
Remeasure the deck after every layer is present.
Use the completed card count, surface and edge treatment to confirm stack height and practical clearance. The change may be small, but a close-fitting tuck box, tray or rigid well can reveal it. Inspect whether decorated edges rub against the insert, catch on a ribbon or leave visible residue on a pale interior.
Keep the approved sample, colour description, stock, face finish, card count, corner and edge process together. State whether packaging samples contain fully finished cards or substitutes. The deck fit checks ensure that a premium edge effect arrives in packaging that can release the cards without damaging the feature it was made to show.
