Pantone printing is a single color, no gradient, the pattern is field, with a magnifying glass can not see the dot. (Generally speaking, Pantone printing costs slightly more.) What are the differences between the two printing visual effects: Pantone printing color brightness is lower and saturation is higher; uniform ink color spot color block is usually printed in the field, to properly increase the amount of ink. When the layout ink layer thickness is larger, the sensitivity of the change in ink thickness to color changes will be reduced, so it is easier to get a uniform ink color, thick printing effect.        2.
