Why is the volume Yilabao picture
If it is ilabo side picture volume that is because of the uneven tension on both sides and in the middle, this may be the material factors may also be on the connection between the connection pieces and the picture is not straight and level.
Suggestion: if you are using PP or paper ordinary material, so keep the picture as smooth with smooth joints bonded together, if it is heat transfer cloth or PVC some of the high-grade materials, as long as the cutting and connecting pieces around smooth bonding is good. The gross pre trimming work must be done well, the picture four must be cut together, it is best not to cut error conditions more than 1mm, the four corners must be kept at a 90 degree angle, bonding time can not pull, must let the picture with the connector _____ Yilabao is my natural bonding designer, the new design is happening, if you have any questions please ask me.
