A colouring structure comprising: a substrate, and a colouring layer disposed on at least a part of the substrate; the substrate and the colouring layer are made from different materials and have different water absorption properties, the colouring structure comprises a plurality of colouring areas and at least one separating area, wherein the colouring area is at least partially defined by the separating area. The colouring structure allows the user to easily grasp the pattern engraved on the colouring structure, which can rapidly absorb the liquid such as ink added to the surface thereof and effectively slow the horizontal diffusion of the liquid added to the colouring layer. For liquids with high water content, the high water absorption of the colouring structure avoids or effectively reduces accidents caused by the use of high-water-content liquids, such as liquid leakage, and liquid spillage and dirtying clothes or body parts over large areas.

The present invention is related to a trackable authentication system of canvas for tracking and authenticating artwork, the canvas comprising: a canvas made by thread; and a plurality of wireless communication chips, that is NFC (Near Field Communication) or RFID (Radio Frequency Identification) chip, each chip being disposed at an appropriate position wherein a plurality of threads are knitted into canvas material for the canvas, and wherein the NFC or RFID chips are for transferring verifiable codes and the codes are provided with tracking and authentification information.

A device for stretching a canvas mounted to a frame comprises a spacer and a screw. The frame has a plurality of side members each mutually abutting at angled ends. A first portion of the spacer includes a central aperture therethrough and two opposing ends or sides. Each end of the first portion is sized to engage a contact surface of each side member. The screw has a threaded shaft adapted for rotational engagement with the central aperture of the first portion of the spacer. The threaded shaft terminates at a first end thereof with a screw head that has a frustoconical side wall and an end surface that includes a tool-engaging recess. Rotating the screw to move the screw head closer to the spacer causes the spacer to push the side members mutually away from each other to stretch the canvas.

A frame assembly includes a frame base and a rear panel including a plurality of side walls that are configured to be received within a plurality of side walls of the frame base. Along an external surface of each side wall of the rear panel there is at least one locking tab that is configured for reception within one corresponding locking opening of the frame base when the rear panel is inserted into the frame base so as couple the rear panel to the frame base in a snap-fitting manner and permit a canvas substrate to be captured therebetween for holding the canvas substrate across a front face of the frame base.

A foldable canvas blank includes a working panel, the working panel comprising a top end, a bottom end, a right side, and a left side; a top end panel flexibly attached to the top end by a first top end hinge, the top end panel defining a top end locking slot extending through the top end panel; and a right side panel flexibly attached to the right side by a first right side hinge, the right side panel defining a right side edge surface distal from the working panel, the right side panel defining a right side locking slot, the right side locking slot intersecting the right side edge surface and extending inwards towards the working panel, the right side locking slot configured to engage the top end locking slot to secure the top end panel to the right side panel.
