Inkjet printing and acrylic product trademarks are both categories under trademark registration. Trademark Classes are part of the International Trademark Classification, used to classify different types of goods and services.

Inkjet printing belongs to Category 16, including printed matter, office supplies and learning materials. These products mainly involve printing, publishing, paper and stationery.

The category of acrylic product trademarks depends on the type of product the acrylic product belongs to. According to the provisions of the International Trademark Classification, acrylic products may belong to different categories, such as Class 6 (metal products), Class 9 (scientific instruments), Class 17 (plastic products), etc., depending on the use of the specific acrylic products.

It should be noted that when registering a trademark, you need to choose the appropriate category according to the specific situation to ensure that the trademark can protect your goods or services. It is recommended to consult a professional trademark agency or legal advisor for accurate classification advice before registering a trademark.
