What is the appropriate grammage of copperplate paper to use as the substrate for scratch off cards?

When choosing copperplate paper as the substrate for scratch off cards, the appropriate grammage (weight) depends on specific requirements and design considerations. Generally, the grammage for scratch-off card substrates ranges from 200 gsm (grams per square meter) to 300 gsm.

If you need a lighter substrate suitable for creating thinner scratch off cards, choosing 200 gsm copperplate paper could be a good option. This weight of copperplate paper is relatively thin and suitable for producing smaller-sized scratch off cards while keeping the cost relatively low.

If you require a more durable and sturdy substrate for larger-sized or more durable scratch-off cards, selecting 300 gsm copperplate paper may be more suitable. This weight of copperplate paper is thicker and offers better abrasion resistance and durability.

However, the specific choice of copperplate paper grammage should also consider other factors such as budget, design requirements, and target users. If possible, it is recommended to consult with a professional printing supplier who can provide more accurate advice based on your specific needs.
