Laser method of scribing graphics

A method of scribing a desired pattern on a material, comprising:

• obtaining an indication of the desired pattern;
• investigating the pattern to determine if the pattern includes elements which are more likely to cause undesired damage to the material when applied to the material by a laser;
• modifying the pattern to change the elements to other elements which are less likely to cause said undesired damage;
• and
• commanding a controllable movable laser based on the modified pattern to write to different locations on a surface of the material.

A method of forming a desired pattern on a material without damaging the material, comprising:

• obtaining an indication of a desired pattern to be formed on the material;
• determining an energy amount to be applied to each unit area of said material based on at least one characteristic of said pattern;
• controlling a relative movement between a marking device that produces a focused beam of radiation which will be used to mark the material, and said material;
• controlling the marking device to output the focused beam of radiation toward said material, by commanding said relative movement, and then, while there is said relative movement between said marking device and said material, to begin outputting said focused beam of radiation, such that said beam of radiation is not output until after said beam is moving relative to said material, to avoid overetching of the material at startup.

A method of scribing a desired pattern on a material without damaging the material, comprising:

• obtaining an indication of a desired pattern to be placed on the material;
• determining an energy amount to be applied to each unit area of said material based on at least one characteristic of said pattern;
• controlling a controllable movable laser to produce an output at a specified energy amount per unit area by controlling at least one of a movement speed of said controllable movable laser and an output power of said controllable movable laser;
• and
• said controlling said controllable movable laser to begin moving relative to the material, and, while moving, to begin outputting its laser beam, such that said laser beam is not output until after said laser is moving relative to said material, to avoid overetching of the material at startup.
