Scratch Off latex
Scratch off latex, also known as rub removable or scratch off ink, is an opaque ink that hides the image or text underneath until it’s scratched off. It’s a popular choice for scratch cards, security codes, promotions, parking permits, bucket lists, and travel posters.
When using scratch off latex, it’s important to choose the right paper weight for your project. For posters, a recommended stock weight of 200gsm is ideal, while for cards, a weight of up to 400gsm is recommended. Scratch off latex is most commonly available in silver or gold, which add a touch of luxury to your print products.
The process:
Both digital and lithographic printing methods are suitable for producing scratch off latex designs on Printed Notepads. After printing, a lottery release seal is applied to the scratch off areas to make the latex easy to scratch off with a coin, plectrum, or fingernail. Additionally, gloss or matt lamination can be applied to further enhance the appearance and durability of the Printed Notepads. It is important to note that the scratch off latex ink is usually the last process, although sheets can be put back through the press if print is required on top of the latex. Scratch off latex is a popular choice for Printed Notepads that require a fun and interactive element, such as promotional items or lottery-style giveaways.
Potential pit falls
Poor adhesion of the scratch off ink or lamination and print set off.
Solutions:
It’s important to allow enough time for the printed material to fully dry before applying the lottery release seal and scratch off latex ink. The drying time can vary depending on factors such as weather and ink saturation, so it’s best not to rush the process.
When selecting paper for scratch off printed items, it’s important to choose a suitable paper type. Uncoated paper, due to its absorbency, is not recommended for use with scratch off latex inks. Coated paper with a weight of at least 200gsm is recommended for posters, while cards should be printed on paper with a weight of at least 400gsm.
The prize can be seen through the reverse
Solution:
When printing with scratch off latex, it’s important to ensure that the weight of the paper is sufficient to block the show through of the image or text below. If the paper weight is too light, the image or text may show through the scratch off area, spoiling the effect. To avoid this, it’s best to use a heavy weight stock.
Additionally, it’s important to be mindful of the colors used below the scratch off area. Highly colored images may also show through the scratch off latex if a heavy weight stock is not used. In this case, reducing the tint value in the area below the scratch off area can help to solve the problem. When designing printed notepads with scratch off latex, it’s important to keep these considerations in mind to ensure a high-quality end result.
The print on top of the scratch off latex is pale
Solution:
When using scratch off latex on printed notepads, it’s important to consider the color of the background as it can affect the visibility of the concealed text or image. To avoid any issues with show-through, it’s recommended to use a heavier weight paper and avoid highly colored images below the latex. If colored text or images are necessary, it’s recommended to use the color black or change the scratch off latex to white. Both digital and lithographic printing methods are suitable for printing notepads with scratch off latex. Once printed, a lottery release seal is applied to the scratch off areas to make the latex easy to scratch off with a coin or fingernail. Adequate drying time is crucial before applying the seal and latex to ensure the print is fully dry. Gloss or matt lamination can also be added if desired.
Scratch off areas are too close to each other
Solution:
When designing scratch off areas, keep in mind that the latex will overlap the designated area by around 2mm. Therefore, it’s important to consider this overlap when creating the design and to ensure that the area to be scratched off is easily distinguishable from the rest of the print. Different shapes and sizes of scratch off areas can be created to suit the specific needs of the project. Printed Notepads can be a great use case for scratch off areas, such as hiding a message or a prize under the scratch off area for a fun and interactive experience.
