Journeyman Inscription
Visit one of the Inscription supplies vendor at any of the major cities and buy a "Virtuoso Inking Set". Keep this in your bag at all times since it is needed to make almost all types of Iscription recipes and Glyphs.
76 - 80: Grab 40 of Dusky Pigment and make 20 Midnight Ink
81 - 100: Use the Midnight Inks that you made and make any Glyph that is orange to you and requires 1 Midnight Ink. Glyphs turn yellow after 10 points here, so then learn new recipes and choose another Glyph. 20 x [Glyph of....]
101 - 105: Make 60 of these - Lion's Ink
106 - 120: Same as above. Use the Lion's Ink that you made and make Glyphs that are orange to you and require only 1 Lion's Ink. Glyphs turn yellow after 5 points here instead of 10, so once they do turn yellow, learn new recipes and choose another Glyph and continue till you reach 120.
121 - 125: Make any Glyph that is YELLOW to you, yes you read it right YELLOW. Orange recipes require 2 Inks instead of one, so at this point it's better to make yellow recipes. You would probably need to make 5-7 Glyphs to reach 125.

126-133: Turn all your Burnt Pigment into Dawnstar Ink. If you don't mill your own herbs and you don't have Burnt Pigment, you can just make any Glyph between 125-140 that looks orange to you. But I would rather suggest you buy some herbs here anyway for Dawnstar Ink.
134 - 140: Use Dawnstar Ink along with Common Parchment that you can buy from Inscription vendors to make 8 Strange Tarrots.
141 - 150: Grab some Lion's Ink that you made before and make 13 of these - Glyph of Lightning Bolts
151 - 155: Make 60 Jadefire Ink. Would need around 120 of Emerald Pigments for this.
156 - 175: Choose between Glyphs and Scrolls that are orange to you and make 20 of them.
176 - 185:Turn all your Indigo Pigment into Royal ink and then make as many Arcane Tarrots as you can. This should get you to 185 or probably even more.
186 - 190: Use 10 Jadefire Inks and make 5 of these - Glyph of Sap. A glyph used by rogues will sell well generally.
191 - 200: Use 26 of Jadefire Inks and make 13 of Glpyh of Revenge.
Artisan Inscription
201 - 205: Here make 50 Celestial Ink. Save these since you would be using these uptil skill level 250.
206 - 210: Make 5 of these - Armor Vellum II. These can again be sold to enchanters for a good chunk of money.
211 - 215: 5 x Glyph of Sinister Strike. Most combat rogues use this glyph while leveling so you would make most of your money back.
216 - 220: 5 of Glyph of Searing Pain here to get to 220.
221 - 225: Glyph of Starfire upto 225. This badboy is used by almost all Moonkin Druids. They sometimes are priced upwards of 25 gold a piece.
226 - 228: Grab some Ruby Pigment and make Fiery Ink until you reach 228. Would probably need to make around 12 of these.
229 - 230: Use some more of Celestial Ink and make 2 Scroll of Agility IV to get to 230
231 - 235: Make 5 of these - Glyph of Dispel Magic
236 - 247: Keep making Weapon Vellum II here until you hit 247. Again you would need around 12 to reach the skill point of 247.
248 - 250: 3 to 4 of Glyph of Cleaving to reach 250. A warrior glyph that will definetely sell for easy money.
251-255: Some more inks again. Getting tired huh? :) Well you're not there yet so keep milling those herbs and make inks until you do. 25 x Shimmering Ink.
256 - 260: 5 x Scroll of Spirit II to get to 260.
