关于Scannable Resumes和italics, underlining,和bold

这里说到“For students applying to computer related positions, high-tech companies or other large corporations realize that your resume may be scanned into a computer database. In these cases:a. Do not use italics, underlining or graphics. You may use capitals to make titles stand out.b. Use a minimal amount of bold.”
请问使用italics, underlining,和bold的影响大吗？ 我看很多resume的sample都有用不少的underlining和bold
希望大家能分享经验
